You keep framing it as getting incensed over other people using ai to write code; but that isn't what it's about. A dev union would not attempt that; it would attempt to ensure quality of life for your class of people (and their families) as much as possible. It isn't about policing entire industries or other entities; it is about DEFENDING those who they would, do, and always have exploited when binding contracts or legislation don't prevent them from doing so.

Union = a group of people defending their rights and that includes the right to a life that isn't at the utter mercy of perpetual enshittification due to the infinite mechanical plodding of heartless (by definition) megacorporations that would never hesitate to eradicate peoples' livelihoods and treat humans as material for the orphan grinder if they could get away with it.

And by the way, they do, if you haven't noticed.
