Appreciate the distinction in the above comment that they are two distinct questions, but also agree the two questions are very connected.

I should've been more specific: I was thinking mainly of the artists v. stable diffusion lawsuit which makes the specific technical claim that the stable diffusion software (which includes a bunch of "weights files") includes compressed copies of the training data. (Line 17, "By training Stable Diffusion on the Training Images, Stability caused those images to be stored at and incorporated into Stable Diffusion as compressed copies", https://stablediffusionlitigation.com/pdf/00201/1-1-stable-d...).

I expect that if the decision hinges on this claim, that could have far reaching implications re: model licensing. I think this along the lines of what you've laid out here!
