Especially when they put the ads in the general channel instead of a dedicated one, makes my blood boil.

Push notifications that aren’t specifically topically opted into get blocked so fast on my phone. I have no patience for wasting my time earning someone else advertising dollars.

I agree. The article also points out this fact. Quoting the article:

Another challenge is that irrelevant or unwelcomed pushes risk having the user disable notifications, uninstall apps, or start ignoring them due to low usefulness. This results in a permanent loss of a channel for sharing timely, useful information, leading to reduced app usage. Unfortunately, as Twitter found, most recommendation engines take a myopic view, over-optimizing on immediate user responses at the cost of long-term satisfaction.

Personally, this problem is so pervasive that I kind of developed a pavlovian reflex to notification dialogs to cancel all without thinking about it.
