It seems like I constantly see “X secure messaging option is actually bullshit because it was purchased by Dr. Evil and Y is actually just e-mailing your messages directly to Xi Jinping.”
Is there an authoritatively “best” one I can just…download and setup easily? Is Signal good? Or do I need to solder a Raspberry Pi to the flux modulator of my home Linux NAS GUI, etc…?
For everyone suggesting signal, have a read here and then decide for yourself.

ETA: when I say “decide for yourself” I mean exactly that. I don’t think all the stuff written in there is true, but some is. You should make a decision based on what you think about those comments, not trust them blindly. But at least you can make an informed decision.
