You're taking it far too literal.

I'm aware of parents who have 6 year olds and 10 year olds using Facebook so that they have access to games and family. The Facebook UI/UX does do nasty tricks to coerce people into providing more information than they prefer.

Did you know that other users can volunteer your information? Someone else can register themselves as your family member, close friend, or classmate at a specific institution, without your consent. They can volunteer your location (city) as well. This was not possible in the past, before the "smart lists" feature. They're literally getting people to fill in the information of friends so that they can be targeted ads even if they chose not to provide that information to facebook. I don't think many people know this.

This is true, I also found that they can still tag pictures of you even if you have disabled/canceled your account.

Forcing people to use their FB profiles as the only means of accessing a service is a downright scary thing considering how much information we know they hold. I wish everyone would have just used openid... I was quite happy with iming/emailing/ and status updates through away messages. We don't need FB. But FB needs us.
