I just switched from Edge to Ungoogled Chromium for exactly these reasons. It used to be a slick, lightweight alternative to Google Chrome, but the last 6 months or so have been a disaster, and the beta version is even worse with the useless sidebar that magically appears when you accidentally hover your mouse in the corner and the hideous rounded corners that turn your Surface Pro into a 1950s CRT. Not to mention the default search one day decided to railroad me into using mainland China censored Bing instead of the international version. It's been so disappointing.

Meanwhile on Android they also started screwing everything up, which led me to switch from Outlook and Edge to k9 and Bromite.

I don't know what's going on in the applications teams at Microsoft, but it's really soured me on the "new" Microsoft, and I've been a fan up until relatively recently too. I just hope VS Code isn't next.
