They’re not serving you the content they sampled, and that makes all the difference.
It’s great how for most of us we’re taught that just changing the order of words is still plagerism. For them they frequently end up using the exact same words as other things and people still argue it somehow is intelligent and somehow not plagerism.
“Changing the order of words” is what it does? That’s news to me. And do you have examples of it “using the exact same words as other things” without prompt manipulation?
Why does the prompting matter? If I “prompt” a band to play copyrighted music does that mean they get a free pass?

If you passed them a sheet of music I’d say that’s on you, it would be your responsibility to not sell recordings of them playing it.

Just like if I typed the first chapter of Harry Potter into word it is not Microsoft’s intent was to breach copyright, it would have been my intent to make it do it. It would be my responsibility not to sell that first chapter.
