now there is always the question how a company used Slack, e.g. just some ad-hoc fast communication channels like "general", "food", "events" or a in depth usage with a lot of in-depth usage, including video conferences, channels for every squad/project/sprint/whatever

but the relevant thing to realize is that there is subtle but very relevant difference between a "social network" focused tool and a work place communications focused tool

and Mastodon has a very clear focus on the former while Zulip has a clear focus on the later
