So let me get this straight. Facebook, a company designed from the ground up to know everything about you and your friends, is offering a small segment of its userbase (paranoid Android users) the ability to connect using Tor.
Discounting the fact that the phone is likely not rooted, and thus not 100% private in the first place.... Discounting the fact that cell data communications are easily traceable from the tower..... You're still using a Tor exit node to connect to a website who knows more about you than you do yourself, and spews out your personal data to the highest bidder 24/7/365?
I just.... i mean...... what?!
