Like, you must know this isn't true, right? I have worked in this industry on and off for almost a decade now, and in general, advertising is only used for users who will never pay. I mean, it makes sense right? You can get $5 for one IAP, and if you are incredibly lucky $5 CPM which is 1000 impressions. In-app advertising is a tiny, tiny percentage of revenue for most mobile gaming companies. That being said, everyone spends on it because the best way to find people who'll play mobile games is to target people who play mobile games.
