But then you don’t know that people in your linked in network find some random interesting.

This. You do not need to react to most things in the first place, much less some noise a social media company wants to show you.

I do appreciate that recent versions of Android (and iOS, I think?) allow granular control over permissions, so you can gleefully shout “fuck you” as you fail to grant notification permission to some game.

I only have it enabled for social apps when someone actually is talking to me, but I just don’t understand why there are notifications for these recommendations or suggestions from some algorithm.

Giving strangers the ability to make your phone make noise is insane

I normally have my phone constantly in the “Alarms only” disturb mode. This has the disadvantage that it may take days, until I decide to check if anyone attempted to contact me.
