Pretty much all "desktop" apps that I see people using these days are built on Electron so yeah it is quite popular. Slack, Discord, Teams, Spotify, VSCode, the list is too long, unfortunately.
Not saying this is on the same level but I find it interesting that apps at that scale can run on Electron but Facebook's old non-native mobile apps performance was awful.
Their performance is awful too.
That was a decade ago.
I saw this with the draw.io desktop app which turned out to just be a big bloated Electron package by looks of it. I have a browser for that already.
