I don't want gif/image/emoji support in 100% of the apps I use, so this point is silly. I dislike Electron apps because they tend to break with the OS UI and force whatever the developer thinks I want on me. I don't. Stop it.
Because they offer a gratis plugin eco-system over the competition that outweighs the disadvantage of running a memory hungry application.
Other than VSCode, my computers are free from Electron virus.
I would say exactly the opposite, not using web-tech for GUIs is disrespecting the users, because the end result is an ugly app with a lot of missing features (gif/image/emoji support for example).
Users seem to love their VS Code/Discord apps written in Electron. I wonder why.
