So in fact it is an improvement. As some apps intersperse ads with useful notifications now.
I'd still uninstall the app.
Would you uninstall Uber if they sent you a coupon via push notification?
I've uninstalled lots of apps when they've sent coupons via notifications. Notifications are to notify me about things I need to act on. They are not a marketing channel. So, yes.
If you had the option to block the marketing notifications but still receive the important ones, would you do that?
If I could set the default for all apps to "block ad notifications", then yes.
That depends. A business that uses notifications for marketing isn't one I want to do business with. If there's a decent competitor I'll switch. If there isn't then I'll decide to begrudgingly put up with it (and probably complain a bit on social media) or to do without it.
So far I've never put up with it and always either switched to a competitor or abandoned the whole thing.
As long as this option is presented before attempting to display any push ads, and not after.
While I got no uber - totally. The taxi service I use sends stuff (receipts mostly) to email - it works well.
Does your app provide real world value like ubers or is it just Tinder for Dogs?
Don't have it installed in the first place. Why feed Uber any business at all? It's a trash company.
