"Local-first apps" are the worst of everything - crappy, dumbed down web UI; phoning home, telemetry, and other privacy violations; forced upgrades; closed source, etc.
At work, I don't have a choice, so it's Google Docs or Office 365 or whatever. And in that context it actually makes sense to have data stored on some server somewhere because it's not really my data but the company's. But at home I'll always choose the strictly offline application and share my data and files some other way.
