That's funny, it's the opposite for me.

I do care. I don't like using Electron apps, even if I have to grudgingly use them a la VSCode. If an app is in Electron or some other slow framework like a Python GUI, my interest immediately drops to zero. If it's in Rust or some other low level language, at least I know it'll be fast.
