That's not necessarily true. I have several free Slack groups that I've used for years. I haven't paid a cent. But it means I've also have Slack installed by default. At every company I've worked, I've supported using Slack because I'm a happy user and these companies have shelled out for paid plans. It feels similar to how MS Office is given out for free to students and sold to companies.
