Cheaper exists (everything from IRC to HipChat to Mattermost to dozens of Slack clones[1]); you're more than welcome to use any of those. The reason people don't is because Slack is the best (great UI, works well, lots of integrations, network effect, etc).
I'd share that Mattermost has gotten popular as a Slack-alternative recently. There's hundreds of contributors and we're now available in Chinese, Japanese, Korean, Spanish, Portuguese, German, French, Dutch and Russian--whereas Slack is English-only.

Right now, Mattermost is most popular among IT organizations looking for an open source, private cloud messaging solution they can control and customize, and we're branching out from there.
Good Competiton always benefits customers.
