The majority of the artist responses were "hard no" in 2024. There's no way the artist demographic such a service would appeal to would be on board with anything even tangent to AI in 2026 (even done ethically) where the professional liability far exceeds the potential revenue.
Most artists I have spoken to don't believe it's possible to do this AI stuff ethically
Maybe they're wrong but I tend to agree. Or even if it is possible to do it ethically, it still never will be done that way because there's just too much money in behaving unethically
