I find the idea that everyone should be instantly available at the click of the fingers to their friends, colleagues, managers, and crapware on their phones absolutely revolting. Push notifications are just interruptions as a service, out of band communications like that should only ever be used for important things but they just get endlessly abused as a form of spam in practice. The advertising industry already has enough tendrils to pry its way into our lives, I'd deprive it of yet another if it were up to me.
What's the justification for allowing it for a certain class of apps, but disallowing it for another class of apps, where the difference between the 2 categories of apps are just the technical infrastructure on which they are based?
Neither is intrinsically right and I think it's good that there's choice, what's winding me up is this idea that everyone should adopt the Google model unquestioningly as though Google are a standard unto themselves. I'm very much in the Apple camp, but it's not out of any love for Apple and more that I don't like the advertising industry and want to keep it as far away from my life as I realistically can. To me push notifications are like popups in the '00s, yes there's legitimate uses in limited cases but abuse is so widespread I'm going to treat every one as guilty until proven innocent.
