They didn’t train it on every available copyrighted work though, but on a specific set of legal questions and answers. And they did try to license them, and only did the workaround after not getting a license.
I think they were talking about the "model giants" like OpenAI you mentioned. Not saying they're correct, but I will concede the amount of copyrighted information someone like OpenAI would want is probably (at least) an order of magnitude more than this particular case.
