The worst thing about Apple AppStore ads is they create a who-can-pay-more rises to the top situation, where previously it was more based on merit.

And In order to make an ad campaign make financial sense, you MUST have a subscription app. Because just getting one download will cost you at least $3 which is already over the cost an app used to cost.

and your conversion rate to paid might be only 10 or 20:1. So you need to make $30 per customer

So as well as being annoying at the moment of seeing them, ads in the AppStore are directly contributing to the general enshitification of apps.
