My job wanted everyone to install Teams on our personal devices. I really didn't want to but reluctantly agreed until I found Teams wouldn't work without some other Microsoft app whose purpose was to reformat my system files into two sections which were personal and work. I said I would not allow that on my personal device and if they needed me to have teams they could provide a work phone. They looked as though it was the most unreasonable thing they've ever heard. I feel like 20 years ago this was the exact thing people were warning us about when installing programs from the internet, now no one bats an eye.
