I worked on a large(ish) contract (tens of millions) with one of Microsoft’s engineering teams where they were implementing an Azure managed version of software we produced. I would regularly refuse to install teams at the meetings, using teams in-browser only.

It also ensured that the technical project manager had to be the one to transcribe anything in our notes into whatever tools Microsoft was using.

While it was never said, the Microsoft engineers seemed to completely understand and never pushed back against my refusal to a) install crapware and b) not take on work that wasn’t mine.

Not using teams: win win.

It is owned by Lenovo, make of that what you will.

Google is also basically American. Make of that what you will.
