Teams won by being bundled with the rest of the Microsoft stack and shoved down captive (corporate) users throats.

I was going to comment that teams doesn't have threads and slack may still win long term, but turns out teams added threads in the last couple of months(1). So yeah.

I'll vouch for this. I moved from Slack to Teams and Teams is clearly an inferior product. That said, I don't think SalesForce owning Slack is really a big improvement.
