This is a huge opportunity for Apple's own ad network, iAd, to really take off. Now that they have the advertisers who are willing to spend money and the information on iOS users who actually spend money in the App Store, this makes iAd much more valuable. Apple loves to control their ecosystem so having their own ad network implemented in majority of ad-revenue-based iOS apps would work out quite well.

Yeah, except the part where iAd was put out to pasture: https://developer.apple.com/iad/

"The iAd App Network will no longer be available starting July 1, 2016"
