Agreed. The thing is that after they have put the price to 50 USD it incentivises indie developers to test it out, which intern results in a higher fill rate for the apps. I think this is just a start, maybe there is a lot more.

Just a question is the CPA also really bad compared to the other ad networks?

It doesn't seem bad, but the CPA doesn't really matter if they can't fill. If Apple is leaving money on the table that means they just don't have the impressions (which is believable, you don't see iAds in a lot of apps).

It could also be a targeting problem (they don't know who is most likely to download), but iOS users are pretty app happy so I would imagine this is the easiest type of ad to convert with. Apple has a huge advantage here as the control the whole ecosystem and are the only ones in the world who can optimize the App Store. Just 25 installs after 1,702 taps for a free app with good reviews seems depressingly low.
