I don't trust facebook with the data I give it now, and they want me to trust locked hardware they made?
Nice contradiction there. If you don't trust them, don't give them that data. If you do you implicitly will have to trust them.
I know this because before I started bouncing their mail I'd get an endless stream of spam from them about how many friends desperately wished I'd sign up.
Unfortunately, scummy is what I've come to expect from them.
