Sounds like you are, because in copyright law there is not carve out for only non-profit education / research. Research and Education can be both profit and non-profit, copyright law does not distinguish between the 2, but it sounds like you claim is research can only ever be non-profit but given the entire computing sector in large part owes itself to commercial research (i.e Bell Labs) I find that a bit odd
That depends on what the layer was, and there is current cases heading to supreme court that have something similar to that so we may see
however commentary is just one type of fair use and would not be a factor here, nor is anyone claiming the AI is reselling the original work. The claim is that copyright law prevents unauthorized use of a work in the training of AI, AI training could (and likely would) be treated as research, and the result of the research is a derivative work wholly separate from the original and created under fair use
