Without a doubt the most dirty and predatory EULA and privacy agreement I have ever had the displeasure of reading, much less signing. And unlike Sony (who at least had the common decency to make this feature optional in singleplayer games), you HAVE to provide this information and create an Activision account just for the privilege of playing the singleplayer and Zombies. Singleplayer doesn't even have co-op! It only requires online functionality for singleplayer so it can data mine and stalk you.

How the mighty have fallen. You know how much ♥♥♥♥♥♥♥♥ I needed to sign up for to play the original Modern Warfare Trilogy? ZERO!
