> After about 2010 companies stopped providing the server binary. Games like Modern Warfare 2, Battlefield 2, etc could be played by communities in perpetuity on private servers. If the next game (MW3, BF3) were terrible, you didn't have to buy the sequel, what you had was "good enough" and you could wait for the next version to be released in 2-3 years.

That's not true about Modern Warfare 2. Modern Warfare 2 was the first Call of Duty game where you could no longer host your own servers. In its predecessor, Call of Duty 4: Modern Warfare, however, that was still possible. For MW2, unofficial servers created by players only became available later on. However, Activision has taken legal action against many of these projects.

Amusingly, all Call of Duties are still basically Quake mods. They've ALL ran on heavily modified quake engine, forked off of ioq3
