I've been all over the place with my thoughts, so it's fair for you to be unsure of how to parse what I said. When making my initial post, I was thinking "this is a coding model, it isn't an image/3d model generation model, so why do they care?". I further interpreted make3 as saying that 3d artists were opposed to AI in general because they view any AI use as trending towards taking away their jobs.

So, what I meant when I said '... otherwise ...' wasn't trying to dismiss the data sourcing concern, but more like "I understand if the data sourcing is the concern, but you (make3) seem to be saying it's about the use of AI in general (ie even if, hypothetically, an ethically sourced training dataset was used for a model), which feels like a weird restriction to me". That was when I added the edit to my initial post.
