Murder and copyright violation are different tiers of crime. The path to justice is also much clearer in murders than in the question of "this model trained on mass-pirated data was distilled against the ToS into this other model which was released for free then fine-tuned and resold for dirt cheap."
If an American citizen murders a Chinese tourist in America, would you expect the American legal system to prosecute the murderer?
And should it be relevant if (hypothetically) China would not prosecute the murder of an American tourist by a Chinese citizen in China?
