Serious question... how?

Well their addresses are now known so one way would be for each ISP to
drop traffic from them. If people don't fix them why should these
devices stay on the net? If say Comcast has a million of them it might
be tricky to scale but not impossible

It'd take a bit of effort and care to aggregate and disseminate the
data to each responsible AS, there'd be risk of bad guys getting the
data and false positives/people spoofing to attack others. They'd also
be building a tool that some might try to hijack for other purposes.

None of that is an excuse to do nothing as is usually the result with
any suggested measure that involves doing work to fix a problem

I know ISPs generaly don't want the support calls but they'll end up
with them and a legislative burden with commerial liability if they
don't sort it out themselves.


"their" Whose addresses are known and who are they known to? I certainly don't know the addresses of anyone involved. Some work can produce Dyn allocations, I suppose.

Bingo. The manufacturer of these decided to build them as cheaply as
possible in order to maximize profit. They neglected even rudimentary
security and maintenance/update measures. Because they could. Because
they chose to. They thus shifted the burden, and thus the cost,
of running them in a secure fashion onto us.

Yesterday everyone paid that cost.

It's time to shift the cost back. Drop all their traffic and when the
support calls come, tell them that they bought a known-defective device
which is an operational hazard to the network, and refer them to
the manufacturer for replacement/repair/refund.

Note: every other vendor out there who might be tempted to cut corners is
no doubt watching this and trying to gauge whether they can do the same.
