12 vs 115 million, according to the second paragraph of the article:

> In its letter, Slack warned Microsoft that “Slack is here to stay,” adding, “We’re just getting started.” But the 4 million users it had at the time would increase to just 12 million four years later, while Microsoft — which added Teams to its 365 bundle without increasing the price — took Teams from zero to 115 million users.

idk where they are getting those numbers though. I've had classes, jobs, etc. which all use Slack, I've never used Microsoft Teams even once. Both my undergrad and graduate colleges give me a free 365 subscription though, which means that me and every other college student could have been counted

As a counter-anecdata, I’ve gone three jobs using only Teams - in one case they had explicitly rejected Slack on the basis of price. My daughter also uses Teams for school.

Same anecdata here (EU) - Kids use Teams for distance learning, pretty much every larger company uses teams (and to some extend zoom) due to the Covid situation.

Hardly anyone even knows slack exists. Everyone knows and uses teams.

That's DAU's - M365 has 200M+ MAU's

Teams isn't a complete subset of M365 though since you can have guest users from outside the org which would count towards the DAU

What you're missing is that M365 is huge in enterprises. Last stat I saw is they've hit 90%+ of the Fortune 500.

Teams got autoinstalled onto my 8 year old Windows 8 desktop.
