Yes, there are people out there using slack as the alternatives aren't that better. To use Microsoft teams the entire company needs to be on office365 and teams isn't that integrated with every service yet. Google chat is supposed to be cool but it has the same issue.

Most of my clients use slack in their companies with teams from 20-25 to around 600.

We use mattermost and its pretty great so far. Not as fancy as slack but gets the job done.
