Why AI art is so controversial

When an artist displays his art publicly he consents to human analysis, praise, criticism, mockery, misinterpretation etc. The artist does not consent to a company using his body of work to train their AI into being able to mimic his exact work. It's worse than a copyright infringement since AI kidnaps the artist himself.
And this is absolutely unethical even if the artist is long dead. You can use a specific artist's work to produce for example pornography, adverts or political propaganda that the artist would never have agreed to work with. It is not art but vandalism.
Contrary to what optimists predicted AI is entering the public consciousness as an merciless abuser.
