Teams doesn't ever come back after uninstallation, and you have to install it yourself to have it in the first place. It isn't bundled.
For about two years now, with any OS upgrade or patch, bundled apps are not installed if you've uninstalled them prior to that OS upgrade or patch.
It's important to keep your complaints up to date with new information, or at least admit that your information is old.
I removed windows a year ago from my last machine and it still had this behaviour. If they now allow uninstalling all bundled apps easily without them coming back after updates then props to them. It's not what I hear from colleagues that still have windows though.
After some digging, it turns out there's a separate installer you have to uninstall. Since when do you have to uninstall installers?
This was on a fully up to date, modern Windows laptop.
