It is (was?) much worse than that. Last time I was forced to attend a Teams meeting roughly a year ago I used Firefox. The UI greeted me with two grayed out toggles informing that neither video nor microphone are usable. Out of morbid curiosity I enabled the responsive tester mode which, amongst other things, allows you to temporarily set the user agent string. I looked up one for Edge, grabbed the first I could find, reloaded the page, and... it worked. Joined the call with full features.

You can not convince me Microsoft isn't an evil company.
