Unity has temporarily closed its offices in San Francisco and Austin, Texas and canceled a town hall meeting after receiving death threats. The company made the call as a precaution against possible retribution after it announced a contentious change to its business model this week.
Ever been in a game forum where the players pretty much worship the developers as if they were gods? It’s way too common. Those people can get crazy protective when they make it part of their identity.
Nope, but I can imagine that to some degree.
Despite that, I doubt gamers are very involved in payment methods of game engines, or even know which game engine their games are running on.
So unless some VERY popular game developers have been out saying expansions for their favorite games will not be released because of this, I don’t see the mechanics for what you claim working at this point.
