There's a lot to criticize about Valve but... Tracking? You can't be serious. They publish everything they track, so it's not like it's a secret or anything. Microsoft, on the other hand, is comparable to Google with the amount of data they try to collect, and God only knows to what extent they're going since the telemetry is the operating system.

If you wanna criticize Valve, look into the state of TF2 (an actively monetized game, filled with AI aimbots that make official servers unplayable), or what they took away from players with Counter-Strike """""2""""".
