For the sake of curiosity, I'm looking into SimpleX Chat's architecture, to answer the question: could I run a fully independent SimpleX Chat stack, ideally that is still compatible with the "official" stack?
Just learned about @simplex and I must say it looks fairly promising as a future #InstantMessaging app to replace #Signal in the long run (I do like #Matrix but it's good to see an alternative and their tech looks solid).
I was not 100% sure about #SimpleX ToS, though, and couldn't find out who the company was, nor their business model (though donation is at least a part of it).
