Maybe for friends and family? But then, if their phone might be compromised by the state...

And telling friends and family they need to setup a Jabber connection to talk you will make you "That guy/girl who...". And if the idea spreads, then talking to n people requires n accounts on n servers. At least Pidgin (last time I used it, which was last decade) supports such a configuration. I wonder if the mobile apps can do the same.

No, it doesn't.

XMPP is like E-Mail and Matrix a protocol which supports federation, i.e. a protocol which specifies how many service providers can cooperate, specifically forward messages to other service providers to reach their users.

what about

- single point of failure of rooms (server creating the chat room)

- media access via 3rd party servers

- gossiping encrypted message access across multiple devices

- encrypted audio-visual (group) communication

- good clients for iOS

- reliable server-side storage of messages (of all(!) chats)

- realistic verification concept for e2ee with multiple devices

Not my project, but I was hoping to see more stuff like https://prose.org/

As others have pointed out, for iOS Monal is good.

Monal looks like something that would be good in 2005, not 2025. There is no way you'll convince people nowadays to use it unless you force them to.
