Jesus is just an uncopyrighted Mickey Mouse if you have no morals. People have been abusing that fact for a long time and have made some pretty abhorrent products.

Obviously there's an ideal middle ground, but what LLMs do is allow free transfer of knowledge while still (mostly) preserving the protections that copyright should be protecting. For example, I can have an LLM give me the entire plot of a book (which is fine), but it won't spit out an exact copy of the book.
