Conversations is indeed a far better alternative here…

• It uses a very popular protocol, xmpp
• works with e2e encryption for text, files, video, audio,
• it can be self hosted,
• it’s fully open source, and has a couple of popular forks (like blabber)
• devs got no funding from intelligence agencies (like matrix has)
• it’s highly efficient (unlike matrix) and runs on the cheapest of vps servers / raspberry pi
