To back up at least the outline hypothesis of this point, this is in Apple's 10-K SEC filing: > If developers reduce their use of the Company’s platforms, including in-app purchases, then the volume of sales, and the commission that the Company earns on those sales, would decrease. If the rate of the commission that the Company retains on such sales is reduced, or if it is otherwise narrowed in scope or eliminated, the Company’s financial condition and operating results could be materially adversely affected. This does feel like the kind of situation that few would want to be at the helm of, if blame was to be passed around in the event of an adverse approach being taken. There's now a number of international regulators all looking at Apple and the competition aspects of their App Store model, and legislators in the US seem to claim to have bi-partisan support as well on the point. If individuals feel they might be blamed, that might explain why nobody wants to step up and improve things.
