Those kinds of statements show a misunderstanding of both the studio and how the games industry works. Any one of those engineers could have gotten into a FAANG the traditional way and doubled, if not tripled, their salary on arguably less involved problems than what they go through creating a real time game.
Its also likely why Schafer chose to take the studio back rather than go the route of finding a new publisher to work under. He still wants to work on games for a little longer rather than get a last paycheck and retire early.
