I agree with your stance on Messenger, yet I have found Cyanogen's Privacy Guard more than satisfying to limit Messenger's "spying" powers. Outside of the US(?

I agree with your stance on Messenger, yet I have found Cyanogen's Privacy Guard more than satisfying to limit Messenger's "spying" powers. Outside of the US(?)

The legal / data privacy ramifications of support knowing a customer's fb profile and all the information contained therein are something I find quite difficult to quantify.
