RIP all the people who have been paying Github for years and never happen to see the notice.
tedivm•1h ago
I think opt out is stupid, but the notice is on every page of github using their banner display right now. They've also blasted out emails.
flykespice•1h ago
At least they are being very upfront with it (I guess?), most companies just slickly add the clause on their routinely TOS update.
SirensOfTitan•1h ago
If they were being honest they would ask explicitly for permission instead of advertising opt-out. Now you might ask: who will explicitly give Microsoft permission to train on their private works? No one will -- and that's the point: this is a form of theft.
malfist•19m ago
And how many people who use git on github go to the website? I only do when my token has expired and I need to grab a new one to push again. Which is every 90 days. Github.com is mostly invisible infrastructure to me.

lkbm•27m ago
If you use Github, you should have an email from ~2 days ago with the subject "Important Update to GitHub Copilot Interaction Data Usage Policy". Easy to skip over assuming it's just one of a million private policy update emails.

If you don't use Github Copilot, this shouldn't effect you, and may be why you got no email. The current headline is fairly misleading--it's about Copilot usage, not private repos per se.

Microsoft services are tech debt. I moved the moment they were acquired and never regretted it.

nottorp•42m ago
I opened gitlab.com and it starts with

"Finally, AI for the entire software lifecycle."

Not very trust inspiring, that.

Can I even have git hosting without anything else being crammed down my throat, or it's just like Microsoft?

eblume•1h ago
I've recently started hosting my own forgejo instance. It works so well! Free tailscale for connectivity. I expose mine over fly.io proxy, also free, but not to be done without caution.
Imustaskforhelp•1h ago
I would've recommended codeberg but codeberg isn't the finest to be recommended for free private repos.

I definitely feel like more can be done within this space and that there is space for more competitors (even forgejo instances for that matter)

mrweasel•1h ago
It's a fair question, but if you need private repos, I think you need to start considering a paid option, or self-host.

If it's really important to you that the repo is private, I'd self-host.

conductr•1h ago
Just spitballing, don’t use these tools myself, but isn’t this something that should be encrypted to really prevent them from training? I personally don’t trust anyone with my data when they pivot to building AI products yet claim my data wasn’t a part of that strategy. It’s too easy to hide/lie.

But it always seemed to me that the UI should run locally with encryption keys that are shared and the service just manages encrypted blobs of diffs that can roll from version to version of encrypted data and that’s about it. Granted I probably don’t know the full workflow, i typically am a single dev on simple projects where I don’t need 99% of the overhead these introduce.

I've been using gitosis to manage private repos for almost 2 decades now. It's extremely easy to host your own repositories.

I just looked up gitosis on github though and it was last updated 12 years ago.... still works for me though.

Overall, hosting your own repos is very easy.

weren't they already using repos for training?
lanxevo3•1h ago
To be precise: the opt-out is for GitHub Copilot training specifically, which has always required opt-in for public repos under their policy. The change Apr 24 is about private repos being included by default unless you opt out. If you're using Copilot in your private repos, definitely opt out unless you're comfortable with that. The setting is at github.com/settings/copilot — takes 30 seconds.
martinwoodward•1h ago
It wasn’t previously opt-in.

Previously we didn’t do any training on usage. However as other products have come into the market they do train on usage. We’ve been training on our internal usage for just over a year and have seen some major improvements. For details see of the types of improvements we’ve seen from training on our internal usage check out this article: https://github.blog/news-insights/product-news/copilot-new-e...

homebrewer•56m ago
You can always ask your parent company to train on their usage. I hear they have incredibly massive codebases: Windows, Office, MSSQL, which stay out of training data for some reason.

I thought neural nets never repeat the training data verbatim, and copyright does not pass through them, so what's the problem?

computomatic•20m ago
That wouldn’t work. Microsoft’s InfoSec team would never let them train a public-facing model on proprietary IP. (It’s a funny joke, isn’t it?)

mentalgear•8m ago
This seems reasonable, maybe too much so.

> If they want to incentivise people to contribute their sources and copilot sessions, they could easily make it opt-in on a per-repository basis and provide some incentive, like an increased token quota.

dotancohen•33m ago

  > takes 30 seconds.
No, it takes an hour of perusing HN every day to stumble upon this. That's 20 hours per month, 240 hours per year, shall I bill it to GitHub or to Microsoft directly?

Corrupting Steinmetz' quip to Ford: it's 30 seconds to flip the switch, 240 hours to know that a switch needs to be flipped.

qaadika•25m ago
It should take 0 seconds, because I shouldn't have to do it.

That's my bar. My time is my time, and anything that takes time from me better have a damn good excuse. Github is not bringing any good reasons to the table to justify making me take my time to protect privacy I've had by default up to now.

doubled112•1h ago
Even the way modern software phrases questions is rapey.

Imagine a man asking a woman “want to have sex? Or maybe later?” out of the blue, then asking her again every 3 days until she says “yes”

ChadNauseam•1h ago
The situation you describe has dynamics that don't apply when your windows laptop is trying to get you to install an update. A woman can't have 100% confidence that saying no won't trigger a man into rage, so just the question being asked at all is already a bit unpleasant. WinRAR trying to get me to buy a license is not as offensive because I know it won't beat me up for saying no.
doubled112•55m ago
Of course. Claiming this is a 1:1 would be wrong.

However, do you think people accept Microsoft backup because they want a backup?

Or do you think they click yes because it makes the popup go away for good?

Wearing me down until I say yes isn’t the same as just yes.

It’s the same dark pattern for the 10-11 upgrade. My father in law managed to upgrade by accident because it kept popping up. He didn’t really make an informed choice for himself. One day he just couldn’t figure out why everything was different.

chuckadams•1h ago

peacebeard•47m ago
"Unconscious people don't want tea." is a great line.
kingstnap•59m ago
There is this distinct lack of giving a shit about the user that you see coming through in a lot of big tech nowadays.

Take this extremely simple example about antenna pod. I can change the order and what buttons show up in the app nav bar. For example I can remove the "home" button or put other things there instead like playback history.

This is a small minor point of the bigger picture. Yet there is this distinct sense in which when using that app I don't feel like I'm beholden to some chain of management in some company deciding they get to decide what I get to do.

Like its almost unthinkable that the YouTube app let you remove shorts or reorder the navigation bar and decide what you wanted to have there.

bilbo0s•1h ago
This.

The belief of business users that this will remain true is grounded more in hope than in cold, dispassionate, business based decision making.

If it's not life or death, encrypt every byte of data you send to the cloud.

If it is life or death, you should probably not be letting that data traverse the open internet in any form.

arcanemachiner•45m ago
Or, they don't train on it, but who's to say they're not harvesting analytics which may or may or not code samples, prompt data, etc. Which are then laundered through some sort of anonymization pipeline, to the point where they can argue that it no longer qualifies as your data, and can be freely trained upon.

Conspiratorial thinking? Sure. But if you've been around for a couple decades and seen the games these people play (and you aren't a complete sucker), then you'll at least be aware that there's at least slight possibility that these companies can get things from their customers that they (the customers) did not knowingly agree to.

schubidubiduba•36m ago
Nothing conspirational about it. Getting data that their users or customers don't actually intend to give is the bread and butter of these companies. And they will do what they can to get it.
worble•1h ago
Pro tip: You could instead spend that money to spin up a forgejo instance for as little as $2 a month https://www.pikapods.com/apps#development (not affiliated, just a happy customer)

Please don't reward these companies with money.

hirako2000•53m ago
I did exactly that. Containerized it and Forgejo simply became a small instance part of the fleet. UI is much snappier then GitHub. And more importantly: zero outages.
encrypted_bird•36m ago

groby_b•53m ago
Github's enterprise version "starts at" $21.99/seat, and requires you to "contact sales".

And I don't see any mention that that exempts you from being trained on. (Yes, the blog says you're still covered, but at that price I'd like to see a contract saying that)

saghm•45m ago
At the risk of stating the obvious, I don't think it makes sense to reward them with money for trying to pull a bait-and-switch on this.
Lio•12m ago
An enterprise licence won't save you, Google, Microsoft, et al have happily been breaking copyright laws for years.

If the publishing industry can't win a case against the AI firms then you don't stand a chance when you finally find out they've been training on your private data the whole time.

They can tell you one thing and do the opposite and there's effectively nothing you can do about it. You'd be a fool to trust them.

mememememememo•1h ago
Yes I think you are right. Even a super ethical company can be taken over. There may be exceptions but it is more luck. I work for a SP500 that absolutely won't dont this and locks down prod access so a rogue staff can't do it. But if Larry or Zuck or Bezos buys them out, who knows.

Context: https://github.com/orgs/community/discussions/188488

TLDR: As long as you aren't using Copilot, your code should be safe (according to GitHub).

  What data are you collecting?

  When an individual user has this setting enabled, the interaction data we may collect includes:

  - Outputs accepted or modified by the user
  - Inputs sent to GitHub Copilot, including code snippets shown to the model
  - Code context surrounding the user’s cursor position
  - Comment and documentation that the user wrote
  - File names, repository structure, and navigation patterns
  - Interactions with Copilot features including Chat and inline suggestions

tomwheeler•9m ago
And even if you read the banner on the site, the email they sent, and the announcement itself, you would not see instructions that mention the specific thing(s) you must change in order to opt out.

Sure, you can poke around in the settings and find one that you believe opts you out, but in lieu of clear and explicit instructions from GitHub, you'll have no way to find out. Only the possibility of finding out later that you guessed wrong.

landl0rd•1h ago
This headline is false; it will not go take your private repos and dump them into a training dataset. Rather, GitHub will train on your copilot interactions with your private repos. If you do not use copilot, this makes no difference to you, though you should probably still turn it off.
hirako2000•48m ago
That's also my read of the flag. But if they can train co pilot on input, I don't see what prevents them from training copilot on the code itself. In a court case they would simply say the opt in meant we can train from input. That's all we did.
olejorgenb•29m ago
To be fair, they display it reasonable prominently in GitHub when you are logged in. Given that, I feel the post title fall under the click bait category. I was fully aware of the Co-pilot opt-out change, but still clicked due the phrasing of the title.
dotancohen•38m ago
What if one of my contributors uses copilot?
computomatic•24m ago
Then GitHub will train on their inputs, which includes your code.

Doesn’t seem to leave non-enterprise projects with much choice but to ban contributors from using copilot (to whatever extent they can - company policy, etc.)

Sohcahtoa82•1h ago
I wonder how effective it would be to sabotage the training by publishing deliberately bad code. A FizzBuzz with O(n^2) complexity. A function named "quicksort" that actually implements bogosort. A "filter_xss" function that's a no-op or just does something else entirely.

The possibilities are endless. I thought of this after remembering seeing a post a couple months ago about how it doesn't take a significant amount of bad data to poison an LLM's training.

munk-a•1h ago
Probably extremely ineffective, it's an issue of scale and unless you really automate the terrible code generation and somehow manage to make it distinct enough in style that it isn't easy to detect and eliminate wholesale then you just won't have the volume to significantly impact the result set.

I'm absolutely sure that there are state actors with gigantic budgets that are putting a lot of effort into similar attacks, though.

martinwoodward•1h ago
No we won’t. Details here https://github.blog/news-insights/company-news/updates-to-gi...

For users of Free, Pro and Pro+ Copilot, if you don’t opt out then we will start collecting usage data of Copilot for use in model training.

If you are a subscriber for Business or Pro we do not train on usage.

The blog post covers more details but we do not train on private repo data at rest, just interaction data with Copilot. If you don’t use Copilot this will not affect you. However you can still opt out now if you wish and that preference will be retained if you decide to start using Copilot in the future.

Hope that helps.

BoredPositron•1h ago
Yes you do? If a user uses any form of copilot in one of his repos except ofc enterprise, says so right in the blog post. These aktshually corporate technicality defense posts aren’t helping, they just end up making you personally look a bit fishy.

jffry•1h ago
It's unnecessarily splitting hairs.

> interaction data—specifically inputs, outputs, code snippets, and associated context [...] will be used to train and improve our AI models

So using Copilot in a private repo, where lots of that repo will be used as context for Copilot, means GitHub will be using your private repo as training data when they were not before.

tptacek•51m ago
No it isn't. Most people don't use Copilot, so this term change won't effect most people. You can reasonably be unhappy about it anyways (or unreasonably still be using Copilot in 2026), but it's still ultra-useful information for them to add to the discussion.
pistoriusp•34m ago
I don't use copilot, but somehow was subscribed... I probably clicked something long ago and it just remained active.
tptacek•26m ago
They're only training on interactions with Copilot, not with the full contents of repos that happen to be subscribed to Copilot.

They "gift you" a free standard plan if you have above a certain (non-transparent) level of stars, I don't think you can even disable your "subscription" if you get it for free.

Next step they'll rebrand search as "Copilot Search" or auto enable pull-request AI reviews (unless you hear about it and turn each off) and we'll all be "users".

> Most people don't use Copilot

So why do any of this at all? You're putting a large part of your customer base on edge in order to improve a service that "most people don't use." The erosion of trust this brings doesn't seem like a worthwhile or prudent sacrifice.

_pdp_•11m ago
Copilot, or "chat with Copilot" is a button that is available on every page right next to the search bar.

I don't have to be a Copilot user to click on it.

This change is malicious, and it doesn't only affect Copilot users. It affects everyone on the platform!

SirensOfTitan•1h ago
Right, but it shouldn't be opt-out only to begin with. It's a dishonest pattern that relies on people not noticing. Honest use of data is a "Caesar's wife must be above suspicion" moment for me -- if this is how you're acting when engaging with customers explicitly, I don't trust you to resist the temptation to tap into my data privately. AI companies already have trained their models illegally against the intellectual property of all of humanity with little consent along the way.

Honestly, if you work at GitHub, maybe you should focus on your uptime -- it's awful.

grepfru_it•1h ago
Back in my day someone would post a HN article to the internal slack in order to sway conversation in their favor. Glad to see its still happening! :D
andoando•1h ago
Thats still pretty bad. Its no longer private if all your code goes through LLM training set and is resurfable to everyone publicly.

Why would I ever use copilot on any code Id want to be kept private? Labling it a private repo and having a tiny clause in the TOS saying we can take your code and show it to everybody is just an upright lie

NewsaHackO•27m ago
I mean, you shouldn't send data to any SaaS LLM for code you want to be private, unless you have had them sign some sort of contract saying they will not train on your use. In fact, it is probably never a good idea to send anything you want to be private off premises unencrypted.
munk-a•59m ago
The initial title and your reply are both too broad to be fully accurate. By April 24th Github will train on private repos (assuming a flag isn't set) but this change is limited to just non-Business/Pro users. So a number of private repos will be effected but it won't automatically affect all private repos (so my panic check on our corporate account wasn't necessary yet).

I am not certain if you're a spokesperson for github - but it's good to be careful in your language. Instead of "No we won't" a lead like "That isn't entirely accurate" would be more suitable. In the end both the original post title and your reply have ended up being misleading.

tadfisher•40m ago
> By April 24th Github will train on private repos

This statement itself is misleading. Also, GitHub probably should have seen this coming.

They are not doing what I initially thought, which is slurping up your private repo, wholesale, into its training set. You don't have to opt out of anything to prevent that.

They are slurping any context and input containing code from your private repo which is provided to them as part of using Copilot.

So, in addition to the opt-out setting, there is an even easier way to avoid providing them your private repository data to train AI models, and that's by continuing to not use Copilot.

layer8•50m ago
In the EU, opt-out is not a legally valid way to obtain the necessary consent. How do you plan to handle this?

Nice try. If you're training on "inputs" to Copilot then you are training on the private repos.

This suspect denial is why I will get my clients moved off of github.

wewtyflakes•49m ago
If Copilot later adds a feature like "Scan your repo for vulnerabilities using Copilot <opt-out>", then that would both fit your criteria, and the baiting outrage of the original poster, in one swoop! Of course, Microsoft would _never_ do that, right?
edelbitter•48m ago
> If you don’t use Copilot this will not affect you.

How does this work for a private repository with access granted to additional contributors? Which setting is consulted then?

dataflow•48m ago
Say someone has a very sensitive secret (say, a Bitcoin private key) in their free private Github repo, and uses Copilot on that repo and touches the secret with it. Would you be willing to assure here that toggling that setting would not affect the likelihood of that secret leaking, and that that likelihood is also unaffected by whether the account is Business or Free?
_pdp_•46m ago
So you will train on data collected from free users working on GPL and copyrighted projects?

And on users that don’t even use github, other than the required account to use CoPilot in Visual Studio.

“Opt-out” is an egregiously toxic and unethical approach to consent and should be illegal everywhere that it isn’t already.

I didn’t think Github had much of a brand left to damage, but here we are.

This is a distinction without a difference, according to the text of that enable/disable dialog,

> Allow GitHub to use my data for AI model training: Allow GitHub to collect and use my Inputs, Outputs, and associated context to train and improve AI models. Read more in the Privacy Statement.

“Associated Context” is the repo. If I use copilot, I’m giving it access to my repo.

I don’t know in all the ways copilot can be triggered, and I’m not certain that I could stop it from being triggered, given Microsoft’s past behaviors in slapping Copilot on everything that exists.

happytoexplain•43m ago
As others have pointed out, this is somewhat dishonest. Which is depressing, if you represent GitHub.
wswope•41m ago
What a wildly disingenuous take. Speaking earnestly from one human to another: your behavior and work is shameful, and you should feel embarrassed by your actions, Martin.

You’re laundering the code of users who don’t opt-in through Copilot users who do, to read in as many LoC as possible. It’s clear as day to everyone not morally bankrupt.

Jabrov•41m ago
Can't you just make it opt-in?

No? Because no one would opt-in, you say?

Wow. It's almost like this is a user-hostile feature that breaks the implicit promise behind a "private" repo.

saghm•38m ago
Yes, you will. This is what the setting says on my account when I clicked the link:

> model training

> Allow GitHub to collect and use my Inputs, Outputs, and associated context to train and improve AI models. Read more in the Privacy Statement

Are you seriously trying to claim that the code isn't input, output, or associated context of Copilot operating on a private repo? What term do you think better applies to the code that's being read as input, used as context, and potentially produced as output?

ziml77•31m ago
I don't like that they are training on any interactions with Copilot by default but training on something that you've put through Copilot yourself is much different than them just shoving all the private repos currently on Github into the training data.
Jolter•25m ago
If you are not willing to migrate out of GitHub, what you can do is to avoid using Copilot on your private repository.
saghm•22m ago
I don't use Copilot, and I don't have anything I particularly care about in private repos on my account on Github. My reaction here is entirely based on principles, not how I'm going to be personally affected.
ziml77•35m ago
Thanks for the clarification. The OP here made me think I missed something in both the blog post about the change and in the available settings.
irishcoffee•35m ago

Appreciate the clarification. But, it's still not great.

To the PM behind this - developers are sensitive to this kind of thing. Just make it opt-in instead?

qaadika•32m ago

"should you decide to participate.."??? You didn't ask if I wanted to participate. You asked if I didn't.

I didn't get to decide to participate. I had to decide not to. You made me do work to prevent my privacy from being violated.

vscode-rest•23m ago
Do you use copilot?
qaadika•9m ago
First response: It doesn't matter if I use copilot right now. It matters if I will ever use copilot in the future. Opting-out is future-focused. What if I said "no, I don't use copilot, so I don't need to opt out", then a year from now start using copilot, completely forgetting about this whole debacle? That's the evil of opt-out. My inaction only benefits them, never me.

Second response: Maybe? I press the little button to auto-generate commit titles and messages that showed up in my Github Desktop. Does that count?

I'm asking sincerely. I don't "use Copilot" as in using it in VS Code or while writing code, so I'm honestly not sure if I am.

mrdependable•28m ago

It's convenient for MS to make this opt in by default for sure.

I started self hosting my own git on a digital ocean droplet with Gitea (1). It’s been unbelievably fantastic and trivially easy to manage experience and I can make them public and invite contrib ans do integrations … I see zero downsides

I see no reason to ever go back to holding my code elsewhere.

Don’t forget git is fairly new

When I first started doing production code it was pre-github so we used some other kind of repo management system

This is a perfect example of where the they’re starting to cannibalize their base and now we have the ability to get away from them entirely.

While I understand the network effect of github for public project, I don't really understand why one would want to use it for private repos.

Rather than defending this absurd decision, GitHub could instantly win back trust by admitting they f*** up and reversing it entirely.

If they want to incentivise people to contribute their sources and copilot sessions, they could easily make it opt-in on a per-repository basis and provide some incentive, like an increased token quota.

This is not hard.

I'm sure this is just me, but I don't mind if AI trains on my public or private repos. I suspect my imagination is just not good enough to come up with downsides.

So far it's been a benefit because coding agents seems to understand my code and can follow my style.

I don't store client data (much less credentials) in my repos (public or private) so I'm not worried about data leaks. And I don't expect any of my clients to decide to replace me and vibe code their way to a solution.

I do worry (slightly) about large company competitors using AI to lower their prices and compete with me, but that's going to happen regardless of whether anyone trains on my code. And my own increases in efficiency due to AI have made up for that.
