Certainly not an over reaction. If an app sends me an uninvited notification then it gets uninstalled and black listed immediately. Even with apps I use regularly, the notifications are blocked most of the day. People undervalue their attention, and phone notifications are trying to steal your attention. Block it all. Even messaging and email apps can be blocked. I'm pretty sure I'm going to check my phone in a maximum of the next 60 min and a message can wait till I'm ready to look at my phone at my convenience.
Amen, my phone doesn't do a thing to draw my attention unless someone is actively calling me or I have willed it do so for an extremely limited amount of time.
It feels so natural to toss my phone aside and not touch it again for a couple hours, it seems weird to me there are people that, like, cannot do that without anxiety
I've personally been wanting to give contacts the ability to choose whether their message should prompt a notification or not. Maybe even several levels up to and including forced max volume blaring alarm for actual emergencies.
And then if a contact abuses it to have a notification on all their messages, I'd be able to override their choice by setting the app to no longer send notifications for messages from that contact.
