People produce countless volumes of unpaid works of art and fiction purely for the joy of doing so; that's not going to change in future.
They don't mind sharing their work for free to individuals or hell, to a large group of individuals and even companies, but AIs really take it to a whole different level in their eyes.
Whether this is a trend that will accelerate or even make a dent in the grand scheme of things, who knows, but at least in my circle of friends a lot of people are against AI companies (which is basically == M$) being able to get away with their shenanigans.
