Does living through it count? :) Once Upon A Time every GMail user was also an XMPP user.

  And now every Zoom and Whatsapp and meet.jit.si user is. This sort of thing didn't really go away, companies just decided to construct walled gardens instead of federate.

    What server is Zoom and Whatsapp using? Their volume must be so intense I'm fascinated to know how they do XMPP for so many.

      WhatsApp used to be ejabberd, IIRC, but I'm sure they're both their own thing now. FunXMPP is WhatsApp's weird non-standard compression mechanism. Basically they took XMPP and replaced eg. <message> with <m> to save a few bytes, but it's been a while since I looked into it, it may do more now.

      Whatsapp: seems they built their own called FunXMPP. Zoom, I'm not sure yet.
