> The worst is the apps where you do want notifications on, like your food delivery apps so you know when your food is at the door, but those companies take that as an invite to send you daily marketing notifications and it all feels like a breach of trust.

Ah yes this is one of my pet peeve. I have resorted to block those notifications too and forced to check the app periodically for any update if I'm waiting for something. Those bastards rely on people eventually tired of that and let ad notifications through but so far I still stand fast. Although it helps that I rarely buy online.
