Good thing that Apple charges $99/yr to get into the App Store, eh?
If I have a free App with no IAP, then Apple gets their $99 and nothing else. I could have 100 or 100 thousand or 100 million users downloading that App, but somehow Apple thinks they only need $99.
Is $99 really enough to pay for this + XCode + app reviewers? No. I'd rather see a real usage-based charge for App store resources instead of skimming % from IAPs.
if a free app is popular and getting lot of downloads on the app store, it is adding value to the iphone. people will buy apple products to use those apps. apple benefits from popular apps being on their platform.
app reviews are mostly automated.
