In my opinion this is the best messager for democracy. For receiving messages while offline you can use Briar mailboxes. I would highly recommend this over many other messagers.
I think you meant to say without central servers
Good catch
I appreciate how light the Briar app is compared to SimpleX. I like the buetooth connectivity to exchange messages without an internet connection, I’ve used the bluetooth connection before. I strongly dislike that Briar uses the same ID with everywhere contact, but I can live with it. SimpleX can generate new ID for each new contact that you send a message so that you never appear the same with any 2 users.
I think the same username is needed for the trust system.
How does it compare to Matrix?
They are two different things with two different goals
All Matrix activity is recorded permanently on servers. Yes, encrypted, but maintain a permanent copy.
I have my own server, which everyone I know uses, including the WUI.
Fuck central servers.
But who you message on Matrix has your activity as part of receieved messages
It’s much more private with less reach and convenience .
