I understand why Apple generally has this policy, because it's easy to move from having an App-price to purchasing "something" in the app where they no longer get their cut.
However it's equally frustrating in areas where it's very clearly not realistic, like the purchase of things like ebooks, etc. Some of which are even worse of a conflict since Apple has similar businesses and 30% is just too large a cut for most services where you're not the end retailer, e.g. an ebook/audiobook store.
Having said all of that, I don't have a good solution to weigh up those two things.
