I tried SimpleX but the VPN kill switch on my phone prevents syncing with my computer.
I use telegram primarily as a note taking app with sync features.
Occasionally I send files to friends, so having easy set up for tech illiterate would be great.
Signal is private. This is c/privacy.
Telegram is not private at all, but has channels and big groups and even, yes, mini-apps.
So Telegram is not an alternative to Signal either, it doesn’t even start solving problems that are solved genially in Signal.
Try Nostr, I dunno. Or VKontakte if you want the Telegram functionality of sending transcripts of your communications to FSB.
