>"A lack of prosecution does not make something legal"
Plainly who gives a flying fuck. The US can claim whatever rules they want and so can China or any other country. On international level all those rules are artificial constructs unless they can be enforced. China can just say for example that they do not recognize copyrights /patents / whatever so it is "legal" for them.
This is illegal in China too, there's just an enforcement asymmetry. I understand what you're saying is de facto true, I'm just taking issue with people saying either
1) its not illegal (it is)
2) it shouldn't be illegal because Anthropic stole training data (thats not how the law works)
