Very true. Even for things that are not really "AI". Or there is no backlash for things that are AI, but are not called that way. To my knowledge, there are filler filters and tools in photoshop that are AI.
Also you could train some AI with your own samples. Or the AI could be trained with "ethical" obtained material. I think the hate stems from the fact that now AI do things previously thought to be a human only task. But much of "art" is just manual skill and imitation with random inspiration. The current main argument against AI with the copyright and "stealing" will fall apart one way or another. At the latest, when they create AI that genereates Art procedurally and not with a database of things to imitate - some of those are so bad, that you can have signatures of the imitated artists surface.
