Call of Duty: Warzone outflanks thirdparty stat-tracking apps with a change to privacy settings

Warzone is never without controversy. A particularly contentious recent development has been the emergence of various stat-tracking apps, including COD Tracker and Warzone Companion, which allow players to check out the composition of their lobbies in realtime and, some argue, manipulate the game's matchmaking by pulling out of 'unfavourable' lobbies.

Players get very angry about skill-based matchmaking in Warzone, not always with good reason, and these apps arguably did little other than pour fuel on the fire. If you want to know how SBMM actually works, here's the primer.

Activision has now put a stop to this by making a change to the basic privacy settings for every player, meaning that the information these apps relied upon can no longer be accessed by default.
