Oh, I appear to have misread your comment as "why developers move to Electron for their apps".
The reason why developers, myself included, migrate to VSCode is really simple: because it's the best all-around cross-platform IDE right now for many scenarios, and because it has a thriving extension ecosystem to tailor it further. But it is that in spite of being written in Electron, not because of it. If Microsoft announced that it is being rewritten in Qt tomorrow, I'd be ecstatic.
Just to give you an example of what kinds of issues using web tech for desktop-like experience can cause:
(Yes, I'm well aware that they fixed it. The point is that the offending code needed to be written in the first place. A native desktop app using 13% of the CPU to render a blinking cursor would be considered an insane bug to have in the first place.)
