AFAIK Amazon uses kind of a loophole by directing the user to their site in Safari to buy Kindle books (that's how it was explained to me, i don't own an iPad or used the app). I don't see what's not ridiculous about Apple's desire to receive 30% of that money. And I as a (potential) user don't appreciate it as I'll end up paying for Apple's cut.
