Is there anything to complain about here really? I'm a lot more upset over Firefox market share slipping than this. Edge sucks, and it's not because people don't test on it. It's because it sucks. It sucks in ways that Microsoft can literally only blame themselves for. Me not testing software in Edge didn't cause the design catastrophe that is UWP to be used for Edge. It's not very developer friendly anyways, it doesn't even like to connect to local servers or display local pages.

I think everyone wants healthy competition in the web browser space, but I didn't want a closed-source browser that didn't run on Mac or Linux with a UI I can't agree with and an already disappointing track record. It only hurts worse that I humored Microsoft once when they forced my browser back to Edge only to discover that practically I still couldn't stand it.

Maybe we should feel bad here, but I don't. If I feel bad for anything it's for the good people at Microsoft that brought us this great piece of engineering delivered in such a disappointing fashion.
