When we installed O365 desktop apps Teams wasn't a thing. I used an administrative install. We installed Skype because about half the company was already using it.

Then one day in June 2019 Microsoft informed me that Skype for Business was going to be upgraded to Teams. I had the option to request a one month delay but I could not stop the roll out of Teams. At some point Click-To-Run (the installer for O365) put Teams on every computer that already had Office. In addition to the Teams app it installed the Teams-machine-wide-installer, which installs Teams to every profile that logs onto the computer, making it run at logon.

Its that part where I didn't get to choose because I already had Skype for Business that bothers me. The machine-wide installer is annoying too. Yes one can uninstall those things but that takes admin rights (some action by IT).

That’s just because SfB was being killed and replaced with Teams. So if you used SfB, it stands to reason that you would want to keep using its direct replacement. It would have been silly to just tell you “SfB is dead” and then not give you a replacement.

If I was informed that Skype was going to die I missed that notification. I was given 30 days notice and no choice. We didn't have to use Teams and could uninstall it but its not clear I could have blocked the install.
