So many stories like this about Slack.
We use Zulip (https://zulip.org/) for our corporate chat, and we've never looked back. It's been good, and it's fully open source. We self-host, but paid hosting is easy to get too if you want.

At this point anyone looking to avoid a price hike like the one described above should probably consider something they'll have more control over.
I'd probably go with my own Mastodon server if I was a company that needed any such communication tool. I'm sure there are other alternatives out there too
you might notice it's 100% free software
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
