XMPP is considered the gold standard of encrypted messengers by both cybersecurity academics and black market criminals, but because its just decentralized code with no clear corporation behind it, there is a lack of a marketing budget or educational materials.

Why use XMPP? Because it’s fast and efficient for use with Tor. It’s easy to host your own server and because it’s fully decentralized, there is no official client for corrupt governments to ban from app stores. This client flexibility gives both users and developers the freedom to participate in the system with a variety of different features. However, different clients work on different operating systems.
