A functioning business doesn't want to arse around setting up a Jabber server, building integration with Jira, creating clients optimised for group IM, or that sort of thing. It's not impossible to do, but it takes time and other resources.
On the other hand, we can use Hipchat - it works pretty well, integrates with anything we want, and somebody else is doing the development work. It's an obvious win.
