Office 365 provides good enough Web Apps to get by without having a native Office installation. I don't have any commercial Desktop Software that I'd need specifically for my work: CRM, issue tracker, Documentation, Figma,... - all available in the Browser.
I think once you're in this other territory then you should consider full native instead of Electron. Why you choose to use an editor housed in a browser engine with tracking baked into the application is your decision. There are plenty of other native editors, both GUI and TUI, a user can choose.
Any app can send network requests, so any app can incorporate tracking. This has nothing to do with Electron either.
But to your original point: yes, the more Electron apps that are really just web apps and can be gotten as PWAs, the better.
At that point might as well make an app.
Offline is one of the biggest reasons to ship a full PWA. This is what service workers are for. The biggest reason to not ship a PWA is Apple barely supports them and you can't siphon as much user data if sandboxed in the browser.
I would LOVE if I could get a basic PWA from my bank that didn't have all of these permissions like trying to read if I'm rooted or not, location access, storage -- none of their business what I do with my device or where I am -- and I could still scan QR codes, check balance, do transfers.
Ah but Google is taking over the Web and such, blame on all that help them achieve their goal.
FTFY.
