Don’t kid yourself – Facebook cares very much about your data! They care about how much they can get their hands on, how easily they can index it, and then how much easier it becomes for them to target ads based on information you have on your profile and apps you use.
In fact, the defaults for Facebook’s privacy settings completely expose your profile not only to everyone on Facebook, but to the entire public including non-Facebook users. Meaning your current and potential employers, people you like and have pissed off, your parents – everyone – can see your Facebook profile.
