Counter-Strike: Global Offensive was a game running all of these things (matchmaking, skins, anticheat ...). After Counter-Strike 2 was released, the servers for CS:GO were shut down. Yet, the game remains mostly playable. Sure, the skins no longer work and there's no official matchmaking, but third parties have stepped up. That's because Valve released (and have always released) server software.

I find this argument quite bad. It was done in the past and it's still being done today. There's nothing preventing any company from doing it except for a combination of laziness and greed.
