@danarel Ok but with applications like Pix-Art Messenger or Quicksy, people can create an XMPP account easily and they support OMEMO out of the box. That part is actually very simple IMO.
There are no user-friendly XMPP apps for iOS though so you are right about the cross-platform issue.
@gandalf86 No ease of use, steep learning curve when it comes to encryption, which apps support it, which dont, very few if any cross platform apps.
Way too many points of failure. XMPP can be great for those who know what they are doing, but I aim to make privacy accessible to everyone.
