Yes.
Google's strategy is simple:
1. The web should be able to control everything (i.e. PWA features not normally found in a browser).
2. Google should control the web (they can index it, track, monetize it, but it has to be on the web).
3. Profit.
Do you think Apple users are super excited at the prospect of most apps turning into battery-draining non-native shitty experiences, instead of using the iOS frameworks? No, they're not.
And push notifications on iOS work as a service, to avoid battery drain, they all go through Apple on a single connection. This is free for all native apps. It can't be implemented for web apps both for technical reasons and because web apps can't be curated, so it'll just be abused like there's no tomorrow.
Have you noticed on the desktop that EVERY SITE asks you for push notifications? This is super annoying and bless your soul if you ever clicked "YES" on any of those. They'll spam you until you die, or eventually ask your nephew to reset your permissions.
EVERY single feature not in Safari, has a reason not to be there. And I'm sick of everyone eating up Google's propaganda and becoming their tools in this. I don't mind Google at all, they should fight for their PoV on all this, and they have a right to expand their business.
But not at the expense of Apple or Apple's users. F that.
