> The issue is pirating books, using them as inputs to math which is then resold as an LLM without compensation to the authors who have clearly copyrighted material.

No one seems to be able to explain what exactly the issue is here. How are authors harmed by LLMs (where such harm is often used to understand the range of copyright in lawsuits)? I don't see anyone replacing authors and their works, such as JK Rowling being harmed just because people can output Harry Potter esque texts. And if that's the case, well, fan fiction has been around for a long time, with no LLMs in its writing.
