People have to start assuming that any communication method in use is compromised. There’s just no way on earth orgs like the NSA would throw their hands up in the air and not find multiple different avenues into an app like signal. Its one of the most downloaded messaging apps. Investment into compromising it is very worth while. People should just assume everything involving a cell phone or computer is inherently insecure. Meanwhile for some analog methods (one time pads, even cupping a hand and whispering into anothers ear, etc), the power balance isn’t so lopsided between the state and the individual as it is with digital communications where everything is probably compromised in some way by now.
