I actually got my girlfriend on to Signal because of all of this. Her last use case was FB Messenger to talk to friends out west on the cheap. I got her to install Signal and she discovered a bunch of people on her contact list were already using it, including her boss. As soon as she tried it and found out there were video and audio chat as well, she was really excited.

There's often an alternative. Myself, I left FB behind a few years back and subsequently lost contact with a lot of people. I didn't try hard to find alternatives, though. Just the same, I've been far more happy and present without it.
