> are closed source, so they are completely unverifiable. They can still be verified by third parties if Whatsapp/iMessage wanted to do it. No company can satisfy security purists, because they can't make a living out of it. We have a secure messaging/voip app. Verified by a third party (they have the entire source code). We use the same protocol signal uses (Axolotl ratchet). You can install applications without app/play store and you can run the server on-premise on your own infrastructure. No google services are needed. But all of that will still not be acceptable by "the community", because we are closed source and charge a license fee.
