Enterprises get Teams for free with O365, or use Slack if they really care about the experience.

Most individuals don't care and use iMessage/WhatsApp. Those that do use Signal since it's dramatically easier.

Teams has not been free with O365 for years now.

I use Teams all the time (although not because it is what I'd choose..).

Mostly just completely free tier, although I do have O365.

On the free tier I think the main restriction is the 60 minute limit on groups > 2?

Don't get me wrong, MS are almost as bad as Google in segregating their chat/video call/conferencing offerings, and even if you did know the names last week, they've probably changed them this week.
