The main problem with this clever mad lib is that published works are published for the express purpose of being read, understood, synthesized, and used as context for knowledge. That is literally the whole reason to publish something. That is all fair use and has been for a very long time. Teachers, critics, writers, everyone who reads, use written works in pretty much exactly this way. If I buy a book about fishing I am allowed to teach what I learn to anyone I want, and even charge for it. Anthropic is choosing not to publish some of its products’ internal workings, as is their right. I find all the righteous indignation about this rather insolent.
