EA did this thing a while back where they saw people were still playing Bad Company 2 on PC on community servers. They updated the game to require a login to EA's server on boot, then took those servers down. Always online is cancer.
That's what every game company has said about every game for decades though! A game disc which installs and plays the game was legally still some nebulous "this provides a licence to play the game which can be revoked at any time", it's only now that the companies actually have the power to revoke them at any time.
