More likely because it's not available on-premise. Check into how many use HipChat instead, because it is.
Either way, this is a HUGE market Slack hasn't even begun to touch. (Although I see they now have a "coming soon!" banner on their homepage.)

Just one data-point, but: my employer went with HipChat because we needed an on-premise solution. (We were moving away from IRC because we needed persistent chat history for remote employees. Using IRC bouncers was considered too high of a barrier-to-entry, given we wanted non-technical employees to join the conversation too).
