You can spot the change in an updatelisted on SteamDB.
Steam Family Sharing allows “family members and their guests to play one another’s games while earning their own Steam achievements and saving their own game progress to the Steam Cloud.” It’s a relatively generous system, although there are equivalent processes available for families playing the same game on console, too.
Players are, predictably, not wild about the feature being initially active in Modern Warfare 2 and now removed after they’ve bought the game.
