I wonder how many people that are really mad about these guys or SE using their professional output to train models thought commercial artists were just being whiny sore losers when Deviant Art, Adobe, OpenAI, Stability, et al did it to them.
squarely in the former camp. there's something deeply abhorrent about creating a place that encourages people to share and build and collaborate, then turning around and using their creative output to put more money in shareholder pockets. i deleted my reddit and github accounts when they decided the millions of dollars per month they're receiving from their users wasn't enough. don't have the power to move our shop…
Companies doing this would make me much less angry if they used an opt-in model only for future data. I didn't have a crystal ball and I don't have a time machine, so I simply can't stop these companies from using my work for their gain.
