I'm in games, where art and tech crossroad. I 1000% empathize for the fact that art exploits, abuses, and underpays even if they at times may be doing more work than a junior web dev.
It's a bit ironic, because a lot of tech offers partial compensation in stock. Something else that really doesn't happen in games unless you work for like, the 3-4 largest studios. So they should at least understand that your compensation is not all based on labor for time worked.
