Hello, I’m doing some research for my family and friends to help them navigate the tech space and recommend them some better privacy focused alternatives. I’ve been stuck with the most important piece: instant messaging.

Ideally I would like something:

• decentralised
• Foss
• Possibly not tied to phone number
• Encrypted
• Not funded by an US or Israeli company
• Fairly easy to use by not tech people

If I manage to convince them, I can’t make them change in a year or so, the alternative needs to be future-proof.

• Signal: is Foss (not completely) but not decentralised (one “wrong” update and we are back to square one) + very much american funded
• Matrix: foss and decentralised but funded by an Israeli company (sorry I really can’t)
• Telegram: phone number registration, not fully encrypted, server proprietary
• Theema: server side not open source
• IRC: no video/audio calls, not encrypted

That leaves me with SimpleX and XMPP, I think (I don’t know much about them). What do you guys use/recommend?

I’m reading [this wiki page].(https://en.wikipedia.org/wiki/Comparison_of_instant_messaging_protocols?wprov=sfti1#Table_of_instant_messaging_protocols)
