You do realize those are usually exclusive for only a year, right? So EGS pays them out for a year of exclusivity and then the devs are free to launch on steam and others.
The thing is, often if they don’t get that first infusion of cash from a deal with EGS (or another investor) they don’t get to complete or even launch the game at all. So it never would make it to the other markets.
Yeah, I’m with you. The entitlement around media (games movies TV) is insane to me.
