I'm 100% convinced the appeal of Electron is that it makes chasing the latest UI trends month-to-month as easy on the desktop as it is on the web. Designers and businesses (and lots of developers) consider this essential, these days, for whatever reason. The above (yes, including the business side) will all complain about how a real desktop program using built-in or otherwise sane-and-stable GUI elements that haven't changed for 5 years looks too "old".
