That’s cool, but also doesn’t sound all that useful.

A fairly significant number of apps depends on Firebase and the like and don’t even have the option to pull notifications otherwise. And virtually every app at least use them.

When’s the last time you’ve seen a chat app that didn’t require push notifications to function? Even Signal uses them. (Though they do so in a way that doesn’t expose any private data)

You just can’t disable push without severely crippling the experience.

Further I’m not even sure disabling them on-device will change anything at all about governments being able to surveil them server-side. Afaik you are only stopping your phone from receiving them, they would still be sent to the Firebase server from the app’s cloud servers.

I don’t think this issue is avoidable other than app developers not using (or using in a secure manner) Firebase or GCM (or ACM) etc
