1) (Mainly) the huge increase in upstream capacity of residential broadband connections with FTTH. It's not uncommon for homes to have 2gbit/sec up now and certainly 1gbit/sec is fairly commonplace, which is an enormous amount of bandwidth compared to many interconnects. 10, 40 and 100gbit/sec are the most common and a handful of users can totally saturate these.
2) Many more powerful IoT devices that can handle this level of attack outbound. A $1 SoC can easily handle this these days.
3) Less importantly, CGNAT is a growing problem. If you have 10k (say) users on CGNAT that are compromised, it's likely that there's at least 1 on each CGNAT IP. This means you can't just null route compromised IPs as you are effectively null routing the entire ISP.
I think we probably need more government regulation of these IoT devices. For example, having a "hardware" limit of (say) 10mbit/sec or less for all networking unless otherwise required. 99% all of them don't need more than this.

Like, I can come up with plenty of possible reasons, and reasons why it could potentially be very bad if ISPs started cracking down on this, but I don't actually know any reasons.
Are any talking about why / why not? It seems like this whole insecure-IoT-device thing would probably dry up pretty quickly if people's internet was cut off when one was detected. They can then turn around and lambast / sue / etc the company that sold it, putting pressure on the source of the problem. Right now there's no reason for sellers to do anything at all to ensure security, afaict.
So... not actually arguing in favor of it, but definitely curious about any stated ISP / core networking system's stated reasons.

Any idea why they don't fix it?

So why hasn't that happened? These are clearly damaging to many, and ISPs are apparently doing next to nothing to prevent it, and it has been extremely clear for a while now that it's going to just become a bigger and bigger problem.

ISPs are starting to feel the pain, so perhaps in the near future they will do something about it.

Or this:
>“The crying need for effective and universal outbound DDoS attack suppression is something that is really being highlighted by these recent attacks,” Dobbins continued. “A lot of network operators are learning that lesson now, and there’s going to be a period ahead where there’s some scrambling and potential disruption going on.”
Uh. No. That's gross negligence if they are only starting to think about it now - the trend has been clear for over a decade, and the IoT threat has been obvious since day 1 and even blasted over public news for the past few years. Their status is pretty much only one of: incompetent, malicious, or they have had plans but haven't acted on them fast enough or strongly enough for [some reason], and that reason isn't something I've seen. Surprises happen, prevention costs money and time, and there are plenty of reasons why everyone isn't already prepared for everything, so I think "incompetent or malicious" is pretty rare.... but what are those reasons?

Or just unplug the culprit. But the key seems to be that the device continues working. Ideally you would just shutdown or disconnect the device. If fridge is infected, the fridge can still fridge, but it no longer has internet privileges.

I can't wait for all of them to switch to IOS-ified devices incapable of installing alternative operating systems or programs, as that would be the inevitable end solution for all these manufacturers if this was implemented.
