Legal precedent doesn't generally cross national borders like that, unless you're talking specifically about international law and precedent set by bodies like the UN or ICC.
When it comes to petitioning to change the law, that's a step further than precedent. Precedent is really just legal cases that had to be hashed out because the laws either don't exist or aren't clear. A person would be well within their right to disagree with legal precedent and try to get lawmakers to clarify or create laws that overrule court decisions.
Automation is a reasonable guess on why some may be worried about LLMs and his they're trained, I just didn't see that in the GP comment. They commented specifically on concerns of their content being used to train models without any kind of agreement or financial incentive.
I should clarify, I meant "will the GP be less concerned if the precedent says training is legal in the U.S.?" The Japan one was just an example of what could happen.
My point was that, if the GP will disagree with such a precedent, then their worry goes further than mere legalities. Specifically, "there isn't clear legal precedent yet whether training models is an acceptable use of licensed work" felt like a non-sequitur to me, because it is unlikely they would care about the legal precedent.
