JustSayin: There is a huge difference between Facebook and Valve/Sony. Sony and Valve are not trying to get as much information from people as they can. If they are, they do a better job of hiding that fact than Facebook.
Cormoran: They do a better job at hiding it.
Their main business is to sell you games, for that to be done optimally they need your information. Facebooks main business is social networking, so of course it's more difficult to hide the fact that they have access to a lot of personal information.
However my Steam page, particularly recently with the revamp, contains almost as much info on it as my Facebook page, and I use it to communicate far more than I do Facebook.
The same can go for Sony and Microsoft (which I notice you neglected to mention, I'm guessing because you agree that they're equally bad). Getting you to think otherwise is the result of good marketing and nothing else. Sony, who currently has a 'for the gamer' image has only just taken away it's HDCP restriction on it's PS4, something they should never have had in the first place. Valve, well, just take a look around these very forums if you want to see what people think of their shenanigans.
facebook wants to sell you everything. hence. they need every information they can get from you.
valce wants only to sell you games hence they collect only info which relates to your gaming habits.

and what do you mean by steam page containing as much info as FB page. im not really FB user. I have account but rarely use it myself. yet it contains way more info on me than steam.
