And the harm you describe is not a recognized harm. You don't own information, you own creative works in their entirety. If your work is simply a reference, then the fact being referenced isn't something you own, thus you are not harmed if that fact is shared elsewhere.
It is an abuse of the courts to attempt to prevent people who have purchased your works from using those works to train an LLM. It's morally wrong.
When you do it for a transformative purpose (turning it into an LLM model) it's certainly fair use.
But more importantly, it's ethical to do so, as the agreement you've made with the person you've purchased the book from included permission to do exactly that.
Reasonable minds could debate the ethics of how the material was used, this ruling judged the usage was legal and fair use. The only problem is the material was in effect stolen.
Sorry for the long quote, but basically this, yeah. A major point of free software is that creators should not have the power to impose arbitrary limits on the users of their works. It is unethical.
It's why the GPL allows the user to disregard any additional conditions, why it's viral, and why the FSF spends so much effort on fighting "open source but..." licenses.
