If I told you Exxon or Microsoft was up to shady stuff you'd believe it, but Blizzard, oh no they are good guys!
Blizzard is a publicly traded company, they aren't your friend, you aren't their buddy, you are their customer. You are merely a few bucks on a spreadsheet to them. Every decision they make is how to increase revenue and profit. They are every bit as soul-less as Exxon, AT&T, or any other big corporation.
Just because their production is fun games and they push this "Oh we're your buddy!" PR spin doesn't mean you should blindly trust them.
