I agree.

I agree, though I dispute the fact that XMPP has failed on the first.

The XMPP community switched to recommending mandatory TLS as a whole just
under two years ago, in no small part due to the issues discussed at length
within the IETF.

This doesn't represent a protocol change but a deployment one, and we
switched after extensively examining the usage of existing, popular servers.

I think "freak" is presumably some kind compliment I'm misunderstanding,
but I'm unaware of any XMPP client which doesn't support TLS. I might have
to get a t-shirt made up with "XMPP freak" on it, though.

Yes, I agree that onboarding is difficult. We've made it more, not less, so
in recent years by trying to avoid a growing spam problem, and this has
hurt usability.

But onboarding is difficult with email, too.

Conversations, Yaxim? Both available in Google Play, although I'm only
aware of Yaxim running back to 2.1; Conversations might require something
more modern.

There's actually no way to upgrade a set of arbitrary clients to mandatory
channel encryption unless you only have one client and you control it
absolutely. This is one of the points Moxie was driving at, and he's quite
right in this.

That said, I think the XMPP community did pretty well - a series of four
test days spanning four months, with a large number of client and server
developers. I appreciate you were caught out by this; I'm afraid that's a
penalty of running an open source desktop that I share; sometimes you find
yourself having to compile your own software when you weren't expecting it.
But the vast, vast majority of users probably didn't even notice.

Thanks, and I appreciate your work too.

By the way, if there's someone from Google here, can you please kill the
broken XMPP system you're running which is causing vast user confusion.

Dave.
