Uploading is infringement. Downloading is not infringement. Nobody (in the US, at least) has ever been successfully prosecuted for downloading. It is never an infringement to view a work, even if that work was explicitly infringing. It is never an infringement to discuss a work you have observed, even if you observed an infringing copy.

If you ask an LLM about a copyrighted work, it does not regurgitate the work; it gives you a book report about the work. It does not create a copy; it creates a report, a summary. This is explicitly protected under fair use

Rightsholders aren't going to win this one.
