> classic game theory

I'm not sure it is in unionisation fights, particularly in an industry as tightly knit as gaming. You're trading a short-term kiss from management for being hated across the industry. That forecloses all kinds of career opportunities outside the majors. In game theory, this sort of repeated interaction is exactly what incentivises cooperation.

As long as someone knows that they're going away from the industry good it's enough for a single defection.
