I tried it and it’s pretty nice indeed. But while I could convince my familie and friends to use Signal, there is no chance that they will use SimpleX. It’s too unknown and “techy” for most of them.

Doesn’t Matrix have a huge problem with metadata or am I not up to date with this?

What about SimpleX Chat? Comes without identifiers, is open source and not located in the US. Relay Servers are located in Germany, UK and Sweden and it’s possible to host your own. Last audit was in 2024. No metadata is stored. Fundings are handled very transparently and presentated on the Website.

Not meaning to advertise it, just genuine interested in other peoples opinion.
