regarding data collection, both android and ios provide multiple ways to review, approve/deny, and manage access to data. it's certainly not perfect but is being constantly improved. And for the HN crowd, you can always run mobile security/privacy tools like mobSF to inspect the app. I'm not suggesting we should have to do this but we can and frankly browser fingerprinting is opaque, also constantly evolving and quite good at tracking and data collection. i'm not sure avoid the better ux of a native app is much worse and given the privacy tools and data available, I generally prefer the native app
