OK, the Chinese models have also hacked people. What exactly do you expect law enforcement to do.
While in the OAI case we can easily treat it as a law enforcement action. When Iran does it? What are you going to do start a war?
The forest in this analog is the internet. As you well know it is filled with threat actors that don't give two shits about your laws. You have been warned. It's your fault when you get burned and have exactly zero recourse.
In the OAI case where we can easily treat it as a law enforcement action, that's a far cry from "who cares who's liable." If the OAI case can be a law enforcement action, we're on the same page. The fact that sovereign nations don't land under our jurisdiction is not an argument against following up or restricting those that do. OAI is the only matter I'm commenting on.
I don't disagree with you - but I am curious as to the amount of power and effort that goes into something like this. I suspect that these hacks into systems are carried out by many agents, running on many MW of compute for a long time - how many actors have access to resources like that ?
