Facebook allows you to control who can see which parts of your profile and your activities on the site. This isn’t a bad thing. Maybe you don’t want everyone looking through your pictures, but you’re ok with sharing the things you’ve liked. Facebook is a security risk because you can’t even control what you want to share with groups of people. So give Facebook a rest. It’s not the end of the world, it’s not even that big of an issue. I don’t get what’s absurd about having granular control over your personal information.”]
