The entire creative industry is full of this stuff, and generally folks know they aren't going to get fair treatment. And it has been a problem for decades.
I mostly know this stuff because I looked. I had dreams of doing animation or something like that as a child/teen. That was back in the 90s, and the stories about bad treatment have continued to current times. Don't get me wrong, at the same time there are folks out there working on this stuff that are living their dream despite it all, but it definitely deterred me. I can do art without it making money with it, after all.
