Everyone I know with a desktop computer installs & uses tons of programs that aren't Chrome. And most of them aren't programmers or other flavors of computer nerd.
The non-nerds also absolutely notice when some stupid Electron chat app makes their laptop hot and takes their battery life from 16 hours to 2.5 hours (ahem, Discord when using voice and/or video chat). Proponents of that tech claim normal users don't notice, but 1) they definitely, 100% do, and 2) more than one might think are even able to figure out which app, specifically, is responsible, not just "my machine's slow and battery's dying fast and I don't know why" (it's usually not exactly rocket science).
