I think it is simply a yearning for freedom. Let's be clear. Artists are often bad boys and girls. They would rather play than study. Ethics must play a part, just as it does in all endeavors, but let's focus on inclusion and access rather than proscriptions for the art itself.
Art is indefensible.
I have seen over the years a gradual chilling effect as academic discourse entered the art making process. Artists needed jobs. They had to teach. Some became theorists of a sort. Others mimicked the language.
