I don’t know about “only Google”, but Apple feels that web push in its current form doesn’t benefit the user (at least, how most browsers currently implement it where every page can ask you for notification privileges). They could gate the functionality behind PWA install, but right now they don’t.
I don't see how this restriction benefits anyone but Apple. What this restriction does is replace an annoyance that doesn't benefit Apple with one that does.
Instead of websites asking to send notifications, they are now nagging us to install useless apps that ask to send notifications and clutter our screens. An honest curator would never even allow these apps into their app store.
This is purely a business decision on Apple's part, nothing to do with user interests at all.
So you're annoyed by a few dozen apps you've installed sending notifications that "clutter your screen", and the solution is to allow the thousands of sites you visit do the same.
No, you don't understand. What annoys me is that Apple has created an additional incentive for companies to clutter my screen with useless apps that wouldn't have any reason to be apps if it wasn't for push notifications.
These "apps" should never be allowed in the app store. They should be websites that get to ask me exactly once whether I want to receive their notifications. Instead they keep pushing and nagging me to install their apps and Apple's policies are encouraging this behaviour.
In some cases, the notifications are useful, but there is no other reason for them to be apps installed on my device.
I want some sites to send me notifications just like I want some apps to send me notifications. I don't want websites to turn themselves into otherwise useless apps just to be able to send me notifications.
