Partially true. I can pay for a book then lend it out to people for free.
The government is in full support of this "lending" concept, in fact they have created entire facilities devoted to this very concept of lending out books.
If I’m rich enough to employ thousands of people I can hire each one of them to borrow as many books as possible then use all the books to train an AI. Perfectly legal. And also very possible.
Point being that the library prevents you from checking out 500gb because of logistical issues. First how can you carry all those books and how can they let other patrons in the library check out books if you grabbed that many? These rules aren’t enforced to prevent “scale” hence why my methodology got around the rules.
