This is mostly just to reiterate myself as the original question was "Does this matter?"

Everything else is simply justifying why it shouldn't, the specifics don't really matter as there is no legal framework to stop china from continuing to distill models and anthropic has proven they cannot use software solutions to stop it either as distillation is still a problem. But I do still believe it wouldn't hold up in court either way as stopping companies from generating training data which was trained on the entire human knowledge corpus is just stealing from thieves and making it 'open' once again so the argument only gets weaker.

What precedents can you cite and specific examples of their applicability. That is, what would Anthropic's lawyers take to court? You can't say because there's nothing there that couldn't be ripped apart by the least legally capable community known to man, HN. That's why no lab has succeeded in a suit anything like what you're claiming could happen. The only reason Anthropic or any other lab would pursue this is political or commercial. They're either looking for help from officials or they're trying to establish a particular market position.
