This is an interesting argument because while Google advertises the PWA concept as benefiting users, many of the features Apple and Mozilla haven’t shipped have been held back over privacy concerns. Reddit works fine in a browser, but the company wants to push you into the native app to get better ad data - they’re not going to support a PWA which gives you more control.
The biggest exception is Web Notifications and while that’s useful the desktop situation suggests there’s more than a little validity to the spam concerns. I would like that for a couple of sites but suspect I’d get really tired of selecting the “never allow” option in prompts.
