that's just unreal, you cannot force anybody to do that
It's quite simple: You don't want to support a product, the players do, give them a way to do so. The game will not be available for purchase after support ends anyway, so they could make the servers open-source without any downsides, and I'm willing to bet there are people out there who would gladly host them.
