I would wager that that vast majority of electron app users, have no idea they are using an electron app and wouldn’t care if they did. I’m inclined to believe that the animosity towards electron is largely held by a pretty small minority.

As a developer I use several electron apps daily on a MBP, I never give them a second thought.

The inelegance of high memory consumption is far less infuriating than the many product and UX sins committed by apps.

Isn't that what the author is saying as well? That Electron apps are memory hungry and eat battery

Quite the opposite, Electron apps will be even more prevalent as they'll run faster and drain much less battery.
