No, I do mean Blizzard Entertainment. Besides the fact they have total independence from Activision in terms of operation. They've also had a long history of doing stuff like this. They shutdown the open source project Freecraft in 2003 long before the Activition merger.[1] Yes, Vivendi owned them at the time. But they have done some equally sketchy things before the Vivendi acquisition as well.

The original StarCraft client silently snooped through the players hard drive and sent the gather information back. They later patched out the spyware "feature" after being hit by a class action suit.[2] I see a lot of fans with the idea that "Bliz is this innocent goodie good game dev who was forced to do evil by their giant greedy parent publisher corps". Trust me, I worked for them. That is absolutely NOT the case. All of these decisions came from with in.
