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…?
Telegram is not a secure messaging app.
Is that the one Amazon purchased?
No, Telegram is a Russia controlled service not using encryption at all unless you specifically turn it on - and never for groups.
Being Russia controlled they put out a lot of disinfo and so way too many people and news outlets still include it in the “secure messaging” category.
