You could argue that most users do not notice or care about this at all so it's a completely reasonable sacrifice to make to have rich applications.

The bit that goes unsaid about Electron is... why?

If the goal is a legitimate app that has the lifecycle of an app that you start up and then shut down today the answer is "just write a web application" and then it "just works" on Windows, MacOS, Linux, iOS, Android, Meta Quest, etc.

Mostly people get pissed about Electron because they have 15 Electron apps running in the tray burning up resources all the time and popping up stuff that covers the tray and other tray applications in those (very rare) cases that you want to interact with something in the tray.

It's a tray problem, not an Electron problem. That is, people use Electron specifically because they want to made rude applications which march all over your desktop in muddy boots: Electron is not a framework for writing well-behaved, polite, x-platform applications; you don't need that, you have the web! Electron is a framework for making rude applications that inhabit your tray, pop-up distracting notifications, etc.

People think they are upset about new technology, but what they are actually upset about is the general consensus being that the new technology has a better value prop.
