I am a big fan of local-first design principles. For most enthusiasts, it's the performance benefits. However, for me, it's the potential it has for privacy in web clients. If you have a web client that only does on-client data storage, you're not dependent on centralized server-side storage for persistence (which is the main privacy-loss hazard). The problem is that the app host still has all the technological freedom to not honor their privacy agreement, and there don't seem to be backstops to that behavior in browsers.
