Good question. I think the main difference is that it is so much easier to visit an annoying website then to download an annoying app. And your GP mentions how a good compromise is to grant this access only to websites you install to your home screen (which I think is a comparable action to downloading an app).

I regularly get spam notifications from major/famous iOS apps. It's always an instant uninstall for me.

IIRC this used to be against Apple App Store rules but I guess they got relaxed for spamming existing customers.

Fastest way to lose me as a customer, TBH, is to disrespect my fiercely-guarded attention span with prompts to spend money while I'm busy being focused on making it.

It was.

Apple themselves have sent notifications of that kind. The rule has since been dropped, I doubt it was ever enforced.

Last I checked, the push notifications that are masquerading as native popup asking user to install “antivirus” are all on web.
