Android has long had PWA support. Almost no one uses it at all. In fact iOS users have long had significantly high web browser usage than their Android compatriots.
"It's because iOS doesn't support it...somehow. Despite entirely separate bases that could be served in entirely different ways, it's actually Apple's fault"
A couple of years ago Apple pretty much fully supported PWAs, including push notifications. Still negligible uptake on either iOS or Android. It turns out that it was the PWAs vs the Apps all along, and had nothing to do with Apple. The web and the average web technology stack has turned so toxic -- those enormous frameworks that yield an atrocious user experience -- that people prefer the app.
Still though, somehow Apple's fault. Increasingly such adherents have to reach to successively more niche weird Google additions to Chrome to justify why somehow Apple is to blame. Because Apple doesn't support the new half-baked AdBlastNoBlock3000 API that Google jammed into Chrome. Etc.
It's just weird. At some point people need to be a bit more honest with themselves about why apps are preferred over PWAs or even just basic websites when an app is avialable.
Um... bluetooth? USB? Sensors? Basically anything dealing with external hardware is a huge hole. I can configure and flash my QMK keyboard from my phone or laptop just by following a shortened URL.
I mean, sure. "Web Sites" work great on Safari! But Apple cares deeply that "Apps" have broader capabilities than the browser, and it does it by crippling progress with PWAs.
Ah yes, the 0.001% of apps. That's clearly why PWAs have made zero inroads, even on Android where Google keeps tossing in poorly considered, completely non-standard APIs.
