We don’t have the legal framework for this type of thing. So people are going to disagree with how using training data for a commercial AI product should work.

I imagine Steven King would argue they didn’t have licenses or permission to use his books to train their AI. So he should be compensated or the AI deleted/retrained. He would argue buying a copy of the book only lets it be used for humans to read. Similar to buying a CD doesn’t allow you to put that song in your advert.
