Sorry, but I still fail to see how it's considered a good to have used $50 million to make "yet another messaging app" (because anything "for the masses" is "yet another thing" because of network effect).

With 50 million, one would have hoped instead that they would have helped improve XMPP, that they would have developed the "perfect" XMPP client that everybody could and would use, and that they would run "for free" one XMPP server with all the features one can expect of a good messaging service while letting the hard-core base have their own server if they want (no need to support the hard-core base, they do it already on their own).

Or maybe with Matrix if one really don't want to contribute to XMPP, but still, with OMEMO, ... I feel like all the "security features" are coming to the XMPP world.

I still believe that if you're not in control of the whole chain (open source client + open source server), you're not in control at all, because you still have to believe the they are doing what they are promising they do, without being able to verify it.
