You could even use an XMPP client with HipChat for your business chat. Though, I'd argue XMPP was one of the factors that contributed to HipChat's demise (it wasn't the sole reason, but trying to scale presence via XMPP proved to be a nightmare).

Presence is the key problem. It scales badly - in terms of compute, bandwidth, and battery. And it's not actually useful. Lose lose. Solution: don't use XMPP.

Matrix had similar problems and most servers just disable presence. Can XMPP not do this?

Who GAF about presence. If the person answers, they're there.
