So if I look at a painting study it and then emulate the original painter's artstyle, then I'm in breach of their copyright?
Or if I read a lot of fantasy like GRRM or JK Rowling and I also write a fantasy book and say, that they were my Inspiration, I'm breaching their copyright??
That's not how it works, and if it is, it shouldn't be!
Sure, if a start reproducing work, i.e. plagiarizing the work of others, then I'm doing sth wrong.
And to spin this further: If I raise a child on children's books by a specific author, am I breaching copyright, when my child enters the workforce and starts to earn money???? Stupid, yes! But so are the copyright claims against LLMs, in my opinion.
