Your kidding right, I mean teams is not great, but compared to the UI rubbish of zoom and slack?

Take for example the whole business of screensharing, if you share a single screen in zoom you get black blocks for all the zoom windows. Yes it makes sense that I don't share the window with participants, but at least let me freaking close it. Similarly moving the controls from bottom to top of the screen reliably confuses early (and even more advanced users).

And don't get me started on quoting text or including math in slack and what is the whole threads section?!
