Rather than a moral argument, I think they're more just disagreeing that the spirit behind copyright law is being violated in that case. So while yes, there may be a rule in there that you may have agreed to, they disagree that such a rule is within the spirit of the law, and may reckon that it should not be a part of it even if it presently is. Like they explicitly mention how they're reflecting on the idea behind it all, rather than producing a legal analysis.

Or at least that's how I read it. I'm sure GP will clarify shortly.

More precisely, the reasoning hinges on the assertion that "Your models are derived works." which I doubt is so cut and dry. There are many processes that take external information as input. That alone clearly can't be sufficient to established that something is unambiguously a derived work.

I read a copyrighted book, it is lossy encoded into the weights of my brain. Am I a derivative work now? No. If that book inspires me to write another book in its genre, it will also not be a derivative work unless it adheres too closely to the original book.
