So it appears as though there is one super massive company which has a monopoly on everything; GenCorp.

I can only assume that this game is part of their scheme to become even more powerful or something. The one billion players marker must have been some sort of starter, and that's why the game shut down! With it, all products made by GenCorp will cease to function, allowing the evil alien race to invade the planet with no problems!
