From what I could infer from some community talks, podcasts and so, I would assert that nowadays they have the problem new hires have been educated in UNIX like OSes and Web.
Thus Windows team gets lots of folks that never coded anything for Windows, and management instead of having proper trainings in place, just goes with Webview2 and Electron all over the place.
I might be wrong, this is more my perception than anything else.
So, in other words, the kids grow up learning and using Linux, right?
You don't see Apple and Google doing the same Webviews all over the place on their OSes, with exception of ChromeOS, which appears to be on the death row to be replaced with Android anyway.
In fact, at WWDC 2025 Apple executives even spoke publicly on the matter against that approach.
