I hear a lot about Matrix being a truly decentralized protocol. But if you register with an instance and it goes down, all users under that instance go down with it. It happened a couple of months ago @ matrix.com and everybody knows it.
Differently, Delta Chat allows users to register same account on different relays so if the main goes down, users can just switch relay and keep chatting.
That makes Delta Chat one step ahead. Prove me wrong.
