a lot of which is motivated by a sense of unfairness
Say you generate a picture with midjourney - who is/are the closest artist(s) you can find for that picture?
Not the AI, not the prompter, so the closest artists you can find for that picture are the ones who made the pictures in the training set. So generating a picture is outright copyright infringement. Nothing to do with unfairness in the sense of "artists get out compete". Artists dont get out compete - they are stolen.
