@baldur I’ve seen many articles like this over the years, and they all in one way or another boil down to “do the work”, whereas the people/companies who choose these toolkits—Electron, XUL, Java—almost always choose them because they don’t want to do the work; someone sold them on the toolkit as a magic bullet solution to X problem (especially, “easy cross-platform app—write for Windows and you get Mac/Linux for free!”) and they took the pitch at face value.
In a way it’s funny to see it happen over and over—but kudos, obviously, to the author for doing the work, telling people to do the work, and even writing a tool to make it easier for people to do the work.
