Ah, the other shoe drops. This is the reason for the blitz of anti-Facebook stories all at once... Legal authority to examine all that juicy personal data Facebook holds.
And if you think you are safe because you don't have an account, I have bad news for you.
The government doesn't have to resort to conspiracies to get your personal data from Facebook, if it wants it, it can get it. We live in the age of PRISM (in which Facebook is a participant,) secret orders, and NSA bulk surveillance. They could literally just build or hack an app that uses Facebook's API, apparently, or buy something from the black market, or in the narrow case get a warrant.
Not to mention... I don't think this would actually give anyone "Legal authority to examine all that juicy personal data Facebook holds." I don't think "legal authority" actually works that way, but IANAL.
This is exactly how I see it. The government already has your “official” details like your SSN, bank account info, address and phone number, but it doesn’t have a very good look into the kind of things you like to do. Having access to that data would be a surveillance analyst’s wet dream.
And if you think you are safe because you don't have an account, I have bad news for you.
