… while every other country waits to see how it goes while drafting plans to emulate this
ajsnigrutin•1h ago
I mean... EU already blocks eg. some russian sites (some countries more effectively than others)... plus all the chat control pressures every year.

Spain is blocking whole blocks of internet during football matches.

UK is making you "show your ID card" to jerk off.

But every such country likes pointing fingers at others, "hey, our censorship is not bad, they have more of it!".

edit: considering the downvotes, HN is not bothered by our censorship either

buzzerbetrayed•1h ago
Why during football matches?
ajsnigrutin•1h ago
So people wouldn't stream the games ilegally... the private entity that owns the rights to broadcasting the games can arbitrarily ban whole subnets.

the end result is well... not good:

sigmar•58m ago
A company using legal action to protect their IP rights is so different from a theocratic dictatorship shutting down the entire Internet to prevent their overthrow. Perhaps you don't follow the news about Iran but these comments are incredibly daft.
ajsnigrutin•43m ago
But that's even worse... Iran is a stuck up country with huge political issues, internal and external pressures, outside countries attacking it while internally they're at the cusp of a civil war. Of course they'll shut down the internet, what else do you expect them to do? It's not like they have many options, nor the government trying to stay in power and crush a coup, even if that means blocking the internet, nor the people who are protesting against it and risking their lives.

But EU countries should be a bastion of freedom, free speech, free access to information, democracy, human rights, rights to this, rights to that... Why do we, the EU countries have to use the same playbook? Yes, banning the whole internet is in one way worse and in other easier, than just banning a list of sites where people can find a way around it, but again, the difference is just in the quantity, the censorship factor is the same. The government gets scared people will see some other propaganda from the other side, and censors it... and even that is done very selectively (daily mail is still accessible from over here, so are fox news and cnn)

With spain it's even worse, because it's not even the government doing it, but the government giving the right of censorship to a private company which clearly abuses that right and the government tolerates this... no court orders, no judges, no way to complain, no fair use, no nothing, a private company decides and the government gives them a blank stamped paper to aprove that.

Yes, i know iran has it much worse, but there's nothing we can do about it here, assuming the internet is banned for iranians and they can't read this or comment here. But EU is doing the same, and we've been tolerating it for years... a site here, a site there,... not everything, but censorship is still censorship, no matter how many sites are censored, and there are people from EU here that should argue against censorship, even if it's just a few sites and not all of them.

FilosofumRex•27m ago
Iran is not a dictatorship, but a republic with thousands of MPs since 1905 and 8 elected presidents since 1979. It subsidize basic needs of its poorer citizens, such as fuel, bread, housing, education and healthcare.

Perhaps, you prefer Arabia, UAE or Israel's internet and find it more to your liking

31337Logic•1h ago
Yeah, you're right. It's totally fair to compare how the EU treats its people to how Iran is treating its people right now. Good job. :-/
ajsnigrutin•1h ago
I live in EU and I oppose internet cenorship, privacy invasion and many other bad things the governments have been doing for years now.

I can't do anything about iran, i don't live there, neither does anyone else commenting here it seems... but many of us do live in EU, and are bothered by EU doing the same thing as iran, even if it's on a smaller scale (for now). You can't support censorship at home and then act outraged when someone else just implements more of it... even though some do, as long as the censored things are the things they personally don't like.

To be fair, i'm more worried about UK, since it's a "test ground" to see how things work before the bad thing are implemented elsewhere, but either way, in my small country we have a saying, that "people should first sweep infront of their own doorways", and yeah, EU and our censorship is my doorway in this case.

TLDR: if we're bothered by internet censorship, we should first stop at 'at home'.

breppp•5m ago
it's a very weird kinda of propaganda I see a lot of lately.

Everything is the same and comparable never mind how hyperbolic. Doubt it? be showered with cherry picked micro facts

There are no ID cards in the UK, so you actually have to get a special jerking off loicense.

Do they have something like intranet with some local services, like in DPRK&Cuba? is this the case of completely losing connection and devices practically bricked for anything other than displaying the time?
siev•57m ago
We do. It's not very good. As in, there isn't even a properly functioning domestic search engine that can match the quality of anything past AltaVista. The only local platforms worth a damn are the ones you'd be using anyway. (the local equivalents to Uber, Maps etc.)

All other platforms (instant messengers, social media, news) are massively unpopular for being horrid to use at best, and government spyware at worst.

To slow down the immediate damage the government has rolled back a few of the recent restrictions, hence why I can access HN. Among Google and a handful of other basic websites. But they are obviously experimenting and trying to figure out how much censorship they can get away with. There is talk of a planned "whitelisting" of the country's internet. Where almost all but a few big important services are blocked completely. This would have the bonus effect of making circumvention using VPNs and other methods even more difficult than it already is.

breppp•14m ago
for someone with a tech background, how hard is it to setup your own tunnel? I'd assume cloud providers are whitelisted due to economic reasons?
e-khadem•8m ago
Lol. That was _before_ these new restrictions. And don't assume that you could setup a simple wireguard server and be done with it. No, it had to be a proper low fingerprint method (e.g., you had to hide the tls-in-tls timing pattern and do traffic shaping). Now, something like dnstt sometimes works, sometimes doesn't. You may be able to open gmail in 10 minutes if it does, and you explicitly have to block the fonts.

Do you think they have a better shot than any other country with an explicit firewall (Eritrea, China, NK, Cuba etc…)
jobgh•1h ago
No shot. The economy is already in the gutter. The productivity hit of a total internet cutoff would be a death sentence
dpe82•54m ago
That assumes the regime cares more about the economic prosperity of their people than about staying in power. So far they seem to care more about power. North Korea provides a model for how terrible the situation can get for every day people in that sort of arrangement.
halestock•43m ago
You can only let that go so far, because at the end of the day you need to pay the military to keep you in power.
tdeck•36m ago
Some level of eonomic prosperity is necessary to keep the government's key supporters (e.g. the ruling class and the army) satisfied.
Imustaskforhelp•31m ago
Their economic prosperity is more linked to Oil than Internet.

Plus, the elites economic prosperity is also linked to their not being protests and for the toppling of govt to not occur and they might be willing to offset some losses to keep the average population in check

Which sucks for the average iranian but we saw how their protests were cracked down with 20-30 THOUSAND people killed and Iran hiding bodies etc.

I have heard that all shops are either shut down or running at the most minimum capacity. Economic prosperity just isn't a question now in Iran.

North Korea unfortunately has given them a path forward. If you're willing to murder your own citizens en masse, you can get away with about anything.

Can ROTW sanction Iran by giving it zero internet access even to "elites" by refusing to peer.
vlovich123•54m ago
You’re proposing a world wide agreement even by their allies? Like they can just tunnel their traffic through Russia or China.

You could try to bifurcate into allied and non allied, but even that would be flawed, especially in countries like the USA where it becomes a first amendment right to try to ban such connectivity. It’s very hard to kill the Internet in terms of connecting peers - that’s kind of the point of its design.

namirez•21m ago
Astroturfing much? I haven’t been able to talk to my family for three weeks. Friends who manage to connect are hopping from one workaround to another because IPs are routinely blocked.
michelsedgh•41m ago
They already have uncensored unfiltered sim cards they issue to their own people, we found that out when X (Twitter) started showing which country you made the accout from and thousands of people had Iran which normal people can't access X without VPN. Its just that they shut off the internet for normal people now, which they hadn't done before.
xvxvx•41m ago
The internet has long been used as a weapon against Iran. It’s the largest espionage machine in human history, backed by the military since day 0.

We already see HN being filled with propaganda posts claiming an ever growing number of Iranians were killed by their own government, all completely unconfirmed. The goal is to get that misinfo to the Iranian people and promote an overthrow of leadership, one which will be favorable to the west and Israel.

I’m no fan of dictatorships but acting like the enemies of Iran aren’t genocidal monsters themselves is beyond the pale. When the Israeli government claims that Iran needs to be toppled to protect the Iranian people, while they simultaneously commit genocide in Palestine, I have to stop and think about their real motives. Trumo wants to bring democracy to Iran, meanwhile his goons are executing Americans who disagree with them, amongst many other things.

Pass.

siev•26m ago
I guess it's time to check "be accused of spreading psyops" off my internet bucket list.

Because I guess you're not interested in my own personal experience of witnessing said people get killed either. Or not exiting my home because I feared for my life. But you seem to have a loose definition of "unconfirmed" [1] so I won't dwell on that. Here's all I have to say:

> When the Israeli government claims that Iran needs to be toppled to protect the Iranian people, while they simultaneously commit genocide in Palestine, I have to stop and think about their real motives.

The Iranian government is evil.

The Israeli government is evil.

Both are, believe it or not, true. Conservative ruling systems often dislike other conservative ruling systems.

> Trump wants to bring democracy to Iran

_Iranians_ want to bring democracy to Iran. And as one of them, I sincerely don't give a shit about what Trump or Israel or anyone else outside of this fucking country wants.

esolyt•21m ago
If you get a chance to talk to an Iranian, try explaining them why it's fine that they're losing access to internet because the internet was brainwashing them to hate their government. Also tell them their government isn't killing or jailing protesters and these are just made-up by Israel and America.

While you're at it, you can try explaining Ukranians why it's fine that Russia is invading them because America is bad.
