alt Hacker NewsI believe the App Store policy is you have to have a setting to disable ads. And Uber actually has it (though it has 8 different channels or so, apparently "Uber teen accounts" marketing was added recently).
I used the setting and am not getting Uber ads (only Uber ride notifications).
Currently my biggest problem isn't ads, it's all the apps now will find ANY excuse to send you a notification in order to keep their "Daily Active User" count high.
You turn off more and more categories and they'll still find a reason.
