Well, I guess i'm going to miss edge, it wasn't a bad browser. it definitely felt faster than firefox...
OTOH, Microsoft did this to themselves. Back when MS actually tried to create a user friendly OS and listened to their users. IE was supported across the entire line of supported OSes. But then under Balmer, they started to use IE and directX (and a few other things) as hammers to force people to upgrade to more recent versions of windows. Combined with a string of moves which pissed of their users and developers has resulted in far more reticence to upgrade windows versions than happened in the win 2.x->windows ME cycle.
Now their applications are suffering because windows 10 is still less than 50% of the windows userbase. So, basically 50+% of windows users can't actually run edge. Similarly with games, A developer that exclusively targets directX 12 cuts out 50% of the windows market share (and a similar share of the game console market).
OTOH, both firefox and chrome work just fine on windows7/8, and somehow so does vulkan, meaning that a brand new game could just target that and gain the entire supported windows ecosystem, much of the mobile, and game machine markets.
Basically there is a layer of management at MS that needs to be fired, because they still think its the 1990's and MS can force any old crap on their user-base and they will suck it up. After all, what are the alternatives (this is sorta still true, both linux and macos are still subpar experiences too)?
