Teams is bundleware, people don't use it because they want to, but because it was delivered by the IT contracts for microsoft products and is hard to un-bundle (until the EU stepped in and they are now making it optional).
I suspected that MS will play some pricing tactics to make this uneventful. A search turned up:
> First, beginning October 1, 2023, we will unbundle Teams from our Microsoft 365 and Office 365 suites in the EEA and Switzerland. We will instead simply sell these offerings without Teams at a lower price (€2 less per month or €24 per year).
For any company already using MS/Office 365, €2 is pretty low but with Slack at $7.25 USD it still seems viable.
