There are few reasons, Microsoft is not bad in gaming. They have Xbox/Kinect and they understand gaming. They are also not making money from user's data by tracking them by whatever means necessary. I also respect Microsoft Research that does some cool tech research that does not necessary get into their products. Social network companies are simply creepy because they make money off of your behaviors and Facebook is doing it as their primary business.
Remind me what did they do for (and with) PC gaming in the last 10 years.And how do you know they aren't making data of tracking you? What do you think Bing is about? Or their massive push towards the POWER OF THE CLOUD? Or the extremely closed Windows Phone platform?
Hackers HATED MSFT only a decade ago - and many still do - and they do just as much shady crap as facebook does.
The whole hate here is irrational in my opinion.
