> But XMPP gives you another freedom. The freedom to choose your user experience. User experience describes the way we use something.

I don't think users care about the freedom to choose the UX. They just want a good UX and that's it.

According the ratings of app stores, users are pretty happy with them.

> PGP has been around in the XMPP community for several years but is currently being reworked into a more modern extension called XEP-0374: OpenPGP for XMPP Instant Messaging that promises to make the onboarding easier for novice users.

I don't get how something OpenPGP will make onboarding any easier for XMPP. New XMPP users who might have an automatically generated account somewhere, still start with an empty contact list. Onboarding is definitely the key issue for mobile XMPP.
