The judge IIRC found that training models using copyrighted materials was fair use. I disagree. Furthermore this will be a problem for anyone who generates text for a living. Eventually LLMs will undercut web, news, and book publishing because LLMs capture the value and don't pay for it. The ecosystem will be harmed.

The only problem the judge found here was training on pirated texts.

The ecosystem is irrelevant, the development of AI is a far higher priority than the ecosystem.
