Well, there's XMPP - it's federated, nowadays all server and clients are e2ee by default, it has less metadata issues than Matrix because it just passes messages, like mail does (Matrix behaves like a network-replicated database)

@lafleur
Thank you! I agree with your opinion on XMPP vs Matrix.
The problem for me is not technical but legal: the XSF (which manages the protocol) is based in Denver, USA.
With the list, we are trying to create an ecosystem completely detached from American jurisdiction for reasons of European digital sovereignty, so XMPP does not meet the criteria.
Even though it is an excellent protocol, with immense regret we have to say no.
@anon_4601 @lafleur you are using core internet protocols every day that has been developed and now coordinated by USA organizations: ICANN, IANA, IETF.
@ag1km @anon_4601 agreed ! We're not going to reinvent http just because the one who proposed it happened to be american, are we ? So long as they're true open source stacks, I would currently vouch for those protocols.
