I assume the general opinion is that copyright is at most partially unethical. That’s what the AI discussion is about too, i.e. artist copyright.
Given the extent to which the copyright system has benefited corporations and publishing companies to the detriment of individual authors and the general public, I'm constantly surprised that it still has many apologists.
