I would argue that it's right call: 1) it's in the world's best interest. I am running llama locally on laptop, and the ability to have the distilled world's knowledge at your fingertips will generate much much more value than what it takes. 2) it does not 'take' any value from the book creators. No one's going to 'not buy a book' because an LLM has been trained with its content (in contrast you might argue that you are likely to not buy a book because you downloaded it from libgen).

Copyright laws are not millennia-old ethical laws that everyone agrees on (like don't steal), they are a modern human construct that were created for the greater good (incentivize creation), and we should revisit them with new tech.
