For me it is when companies/services market themselves as donating to XYZ cause if I buy their product. If they want to donate, they should have already done that with the money they have. Asking me to give them profit so that they can donate is so obviously pretentious.
This one needs to be illegal.
Apps that you need push notifications turned on for, but also serve ads.
For example, where I live the company that does riding sharing also does all kinds of deliveries. I get notifications about all kinds of restaurant deals.
The version of Amazon we have sends all kinds of unwanted messages from sellers if you add an item from their shop to your cart. It can be turned off, but it needs to be done one by one manually.
Even the mobile wallet apps that we use here send all kinds of ads.
Like, I need notifications about payments and that is it. Stop giving me full screen popup ads each time I open the app to make a payment. It just slows me down and frustrates me.
Some android phones have the ability to long press on a notification, click on settings, and alter what kinds of notifications you receive. I’ve had a few instances like you describe, but where I’ve been able to turn off “special deals” or whatever. I think implementation of this is done by the app developer though, because I’m sure I’ve had some apps that had no useful settings. Example screenshot of Gmail settings:
That’s a cool feature. I doubt the app would offer this as they probably do not want to allow the notifications to be turned off.
