Yes, Facebook is a company

It's no surprise that companies try to make a buck whatever way they can. Social networks aggregate tons of information from their users, and sooner or later they share that information with third parties. This may be old news, but Facebook has a dev platform and the default privacy settings allows developers access to almost everything in one's profile.

As you can see in the picture below, almost all of your information is free for perusal by anyone who joins the dev program. Facebook does include a disclaimer in bold on that page:

If you check any items, your name, networks, and list of friends will also be shared. If you uncheck all items, no information about you will be shared.

To restrict use of your information, do the following:Click "Privacy" on top right.Under the "Facebook Platform" section click"Edit Settings".Scroll down to the bottom and UNCHECK ALL of the items under facebook platform.
