Empathy, the Gnome messaging software, has yet to implement end-to-end encryption because of this mode of thinking. Rather than implement OTR they said they felt it was better to implement a protocol with E2E built in since it would be supported by native clients (what does that even mean for XMPP?). As a result, their users never had end-to-end encrypted messaging at all. That is what being religious about these things gets you. Signal is completely closed and its users are at the mercy of the developers. XMPP+OTR was a kludge but it worked and the only reason the outstanding problems were not resolved is that the cryptographers behind OTR decided to focus on Signal. Matrix is basically irrelevant right now and whatever security benefits it might have are equally irrelevant because very few people are using it.
