The only reason I see that makes the app store the best place for this is that app store users like to throw money at silly things they don't need, and the primary reason this is true is because apple has fostered an environment that makes it true. If apple feels that the presence of a drone strike app will make people less inclined to spend money in their store, that is exactly the sort of decision that this app developer is trying to capitalize on. It just went the wronG way for him this time.
