> These apps often require ridiculous invasions of privacy - refusing to work if you don't give them full access to location, running in the background[...]
The "full access to location" to that is likely because of Android's broken security model, which made asking for location the only way various apps had to bind to some physical device. It's apparently being fixed[1].
As for running in the background: Isn't that because it needs to poll for and receive the notification?
You can do notifications without polling in the background.
Even Facebook Messenger doesn't require the "run in the background" permission, and yet all sorts of cheapest Chinese bidder IoT and Appliance garbage apps check for it and refuse to run if you don't grant it - such as the app for Thinkware dashcams.
