Agreed. I don't understand how training LLM on publicly available data is an issue. As you says, it doesn't copy the work. Rather the data is used as "inspiration" to stay in the art analogy.
Maybe I'm ignorant. Would love to be proven wrong. Right now it seems to me that failing media publishers are trying to do a money grab and use copyright as an argument, even though their data/material isn't getting illegally reproduced.
The general "understanding" of left leaning ideologies in America is sooooo bad. Left == commies! Weird that America has lots of great relations with Socialist countries. Trump even want people from Denmark to move to America and yet pretty much all Dane's are socialists.
