it’s not even close to that black and white… i’d say it’s a much more grey area:

possibly that you buy a bunch of books by the same author and emulate their style… that’s perfectly acceptable until you start using their characters

if you wrote a research paper about the linguistic and statistical information that makes an authors style, that also wouldn’t be a problem

so there’s something beyond just the authors “style” that they think is being infringed. we need to sort out exactly where the line is. what’s the extension to these 2 ideas that makes training an LLM a problem?
