You sort of have a point, but users shouldn't have to pay the price for better UX for devs, the companies making operating systems should.
Even non-power users pay the cost, they just don't realize it yet.
But as long as users still need Apple/Microsoft/Google's platforms to be able to run Electron apps, those corps won't care, specially if it takes devs away from the toolchains controlled by them.
Maybe if someone can come up with a pure Electron OS that can run on any device, it might force Windows/Apple/Android to agree on a universal native UI API?
