End-to-End Encryption is good but metadata protection counts as much. Names, group descriptions and memberships, avatars, who talks to whom ...

Both #deltachat and #signal go to great length to protect all the metadata that WhatsApp grants itself gratuitously. #Matrix stores similar scales of metadata on their servers, even if you can choose which server stores it.

Everything is better than #Telegram which additionally stores message contents in all group chats/channels and most 1:1 chats.

@delta Do you have a position on SimpleX?
@faket we are lightly following its developments but are not impressed by its UI/UX, and also don't think they particularly care for resilience (they are blocked since >15 months in russia, and don't do much about it, for example), also they don't appear to care much for people with small data plans and bad networks, and rather tune everything for resource-rich always-connected users. They also appear to be going down the crypto-coin rabbithole quite a bit. YMMV.
