Mostly because M$ has a browser based on Chrome after failing to gain significant market share with their own and supporting 72% of the browser market share (Chrome + Edge) is good enough for them. Maybe if more people used Firefox, they'd be persuaded to support it. Currently Firefox usage is around 9.2%. I'm using Firefox so it doesn't work for me either. I was using their web app before they decided to ditch Firefox. Now I am forced to use their stupid desktop app. If they decide to push ads I will just tell my colalborators to contact me via e-mail or switch to Wire.
