Link to article from main Lemmy❤️ developer about Signal privacy. Mostly fair points. I kinda distrust so centralized services but basically we have no other options (Matrix is buggy in many aspects). What can you say about this article?
There's Session, which uses some kind of shitty blockchain version of not-quite-Tor. Every user acts like a not-quite-onion-service and your username is a not-quite-onion-address.
