Ask HN: Why Always the Same Ads in iOS?

In my ads on iOS – when playing a paid videogame – I always see the same stuff: Fishdom, Bingo, Dominoes, Home Escape, they are so obsessive, frustrating and manipulative that make me hate playing the videogame.

Why there are so few software companies advertising in my iOS? Why I see always the same gambling apps? How can I see instead ads from "real" apps that are not scams / gambling like these?

Not only these ads are even showing screens and gameplays that are very different once downloaded, they do have tons of negative reviews yet a very higher rating. They also force me to interact with them in order to start that silly 30s timer until I can close them. Sometimes they crashes. Sometimes they cannot be closed

I'm very curious about how the industry of ads - especially gaming - is working. How is acceptable from a company like Apple that they are advertising spam and scams?
