EDIT: Thank you all for detailing your experience with, and hatred for, this miserable product. Your display of solidarity is inspiring. Now, say it with me:
It's particularly bad now that it's forcibly embedded into every computer, and at the forefront.
You can't hit Win-C by mistake any more, since Windows will instead open a window to "chat with friends and family" by trying to install Teams. (Which makes it particularly bad on my end is that the install broke, so it will randomly pop up later with "Cannot install teams at the moment. Please try again later.")
