I was originally pretty excited about Edge, even as a non-Windows user. I'm not sad to see IE go. But times have changed, and the balance of power has shifted. Now that IE is no longer dominant, simply losing it only worsens the browser oligopoly. Replacing it with a new rendering engine that's designed from the ground up to be standards compliant, though, makes things better. It could have meant that Firefox could once again have had an actual ally in trying to prop up a free and open Web.
Microsoft giving up on Edge's rendering engine and replacing it with Chromium, though, means that, ironically, the death of IE ultimately served to further exactly the bad situation that it once emblematized.
We're just trading one leadership figure for another.
