Their Teams uninstaller isn't quite as good - it just doesn't uninstall all the crap that the Teams malware has left behind. I still have a stray MS Teams audio device left on my macOS machine.
The Skype for Business "installer" is too good at removing stuff.
Skype for Business stop working, I run "Repair" on the installation, progress bar zips to completion. Skype for Business is now gone. Oh, and so is the rest of Microsoft Office.
I actually believe in filing as few bug reports to Microsoft as possible, that way they don't have any signals about what to research. Hopefully it'll waste some amount of their resources, no matter how few.
