With (popular) messaging apps now subject to draconian measures to introduce a backdoor, I am now skeptical of these messenger apps, since all an intel agency has to do is push a backdoored binary down the wire to a device, and the user is (usually) unaware that their messages are tapped by the agency. Even with reverse engineering of the app, it could be difficult to determine if it's compromised or no longer 'privacy aware'.
