One can believe in the capability of a technology but on principle refuse to use implementations of it built on ethically flawed approaches (e.g., violating GPL licensing laws and/or copyright, thus harming open source ecosystem).
What you see as copyright violation, I see as liberation. I have open models running locally on my machine that would have felled kingdoms in the past.
AI is more important than copyright law. Any fight between them will not go well for the latter.
Truth be told, a whole lot of things are more important than copyright law.
