Actual co-ops have individuals with hiring and firing power
Who are democratically decided, sure. Even if it's true that there was no surplus value extracted it doesn't matter because the workers are still alienated from the product of their labor. When they attempted to have more democratic control over the process of making the magazine, they got fired. Sounds like a capitalist boss worried about losing control, to me.
He doesn’t even own the business, and it’s structured such that no owner can skim off whatever profits are generated (it’s a not for profit).
As someone who's worked in the non-profit sector, trust me when I say that this means basically nothing. These set-ups can often become even more exploitative because they're generally set up to do work that people consider "good," like organizing workers or fighting climate change. But regardless, the pay isn't the issue here. It's about power dynamics and how the boss reacted when the workers attempted to organize to change those power dynamics.
Meanwhile I'm over 300 lmao, like you said it really depends. And this is probably the best county to be a PD in the state I'm in, I've heard it's worse everywhere else here smh. Keep fighting the good fight!!!
