Didn't Microsoft Teams soundly defeat Zoom, Slack, and all the others? I was under the impression that Teams has at least an order of magnitude more active users than any competitor.
But MS and good product naming, well...
When it's bundled with O365 and shares admin tools, accounts etc, there's no wonder companies pick it.
I don't know anyone who uses it outside of work.
Wasn't too bad when most were under ICQ, AIM or Yahoo messenger... but after FB, Google and MS got in the mix it just went to hell mostly. Still is. I mean I have half a dozen messenger apps on my phone each with half a dozen contacts that thing $FOO messenger is better for privacy/comms/etc.
