Electron came out of Atom, which came out of GitHub, which Microsoft now owns. Obviously Microsoft is a vast empire and there's no reason every team will adopt other teams' work, but it seems curious to hear that electron was dropped for what's effectively the same tech (chromium rendering a web app).

The article tries to explain why Edge Webview2 is better, but I don't find the explanation very compelling. Chromium doesn't seem to be the problem, because both technologies use chromium. So is it the Node bits? Configuration of chromium inside of electron?

From the outside looking in, I find it curious that they didn't just change Electron to do whatever magic they wanted it to do. Certainly they have the expertise and resources.
