That's correct. Our main differentiator from Signal/WhatsApp/Wire/Telegram/etc is that we have no centralized messaging infrastructure. Users are free to run their own servers, or connect to any 3rd party providers they trust. We also have integrated Tor support, but plan to remove that once iCepa reaches maturity.
Most public servers are pretty bad in terms of modern XMPP features [1]. Trust is also a big issue, but one of our goals is to solve this problem by making it much easier to run your own server. We currently default to Dukgo for new registrations but they don't support many of the XEPs required for a good mobile experience (0198, 0313, 0357).
