And I'm not arguing that apple needs to reduce the fee. They can charge whatever they want for their IAP system. But, other companies that have software/services that are cross-platform, should be allowed to use their own payment processors without paying additional fees to apple imo. Apple should be able to put up the message that hey, you're leaving our ecosystem, you're on your own, blah blah. But I don't see a reason why they should also get a cut at that point.
