> Seriously, go use products like Google Hangouts

Corporate standard at my place of work. I hate Hangouts with a passion. It's the worst messenger, feature- and UI- wise that I've seen for years.

> Microsoft Teams (Microsofts's surprisingly better clone of Slack)

No it isn't. Used Teams at another company which adopted it as the standard. Couple of years ago. Feature-wise it was like a proof of concept, very early access.

> Additionally, the major revenue source was Business tier use, which Microsoft dramatically improved by integrating it with their other cloud-based business suite applications.

Again, I worked at another company where Skype for Business was the standard and nobody ever used it unless they needed formal IT help or something.

All the teams I'm acquainted with at my current place refuse to communicate on Hangouts and, in violation of corporate policies use something else like Slack or Mattermost.

Teams a few years ago is not a good comparison it has evolved a lot since just a year ago. Wile slack is getting more bloated and messy, through currently okey to use.
