"Centralised messenger Signal has just announced that they are making part of their server software closed source. They claim it is to fight spam, but by using closed source they make it impossible for outsiders to verify the truth. This is worrying.
We really, really need a fully open, decentralised alternative to Signal.
There are several alternatives being developed, please support them:
➡️ @matrix
➡️ @delta
➡️ @briar
➡️ @Jami "
I like Matrix and use it along with Signal, but it leaks significant metadata compared to Signal https://gitlab.com/libremonde-org/papers/research/privacy-matrix.org/-/blob/master/part1/README.md
It’s not a real solution, an alternative, yes, but only has federation/self hosting above Signal. Signal leaks significantly less data.
