Of course it's the intention of the user that matters here, I just see that these models give easy access to make extremely derivative works from existing artist's work - and I feel that's an unethical use of the unethically sourced models. Anyone finding their own artistic voice with the tools, I respect that, those people are artists - but training with the aim to create derivative models, that should be called out.
