You're not dealing with an excel spreadsheet here. Apple has rules that are enforced by humans. If you try to cheat them out of the 30% they believe you owe them, they will punish you for it by removing you from the store. So far, very few (if any) companies have gotten away with it. You can't just point to a tiny asterisk or typo in the terms and get them to go 'oh well I guess you got us then'. They have the power. This is why you can't purchase kindle books from the iOS app and have to use a web browser to do it. Even that is kind of an exception (people already have existing Kindle libraries, so it's not really reasonable for Apple to tell them to go screw themselves - but you bet they're gonna demand 30% of on-device purchases!) One pattern I've seen however in modern mobile games is that instead they use an loyalty program, where if you buy direct from them (at the same price) they give you free bonuses that you don't get on the iOS store. That satisfies the "equivalent price" and "no crippling" semi-rules but I suspect eventually Apple will decide to punish it too.
