This also skips over with some hand waving that a lot of mobile app uses cases simply can’t be replicated with web sites. Take gps or smart home control as two easy of the top of my head example the author skipped too.

Also the fact that people here would rather have their info stored in the cloud vs local on device is interesting.

I do mention cases where the browser model doesn't work, like accessing Lidar sensors. Just didn't want to bloat the post with too many examples. But I totally agree with you on this front: not everything can be done as a PWA.
