Yep. Perhaps emphasis on the "bundled with."

Unfortunately, I suspect Slack use at my company grew largely out of IT's unwillingness to spin up a web-facing IRC solution, and their unwillingness to expose internal services to the web. The latter is very convenient for sales or on-call employees. As a result of that security posture, we instead share tons of company secrets on a 3rd party service. It's kind of a weird local maxima.
