Perhaps it’s my profile but all ads I get for apps is pay to win scam games. Surely Apple profits from these but I don’t think that’s the kind of profits Apple is after.
Those are the apps that will run more ads if targeting is crippled. They take a spray-and-pray approach by buying up all the cheap, untargeted inventory. If you see a lot of them, that means you probably aren't being tracked by the ad network.
That’s an excellent incentive to stop using the apps that are displaying the bad ads.
