Apple absolutely does anything they can to avoid their platform being beholden to another vendor's technologies. Their execs have spoken on this several times; it's a key part of their strategy. They have a strong confidence that the results will be better if they take pervasive responsibility for their customers' experience. We'll see. Everything's a tradeoff. It seems perfectly reasonable to me for developers to be wary or even turned off by Apple's tactics. But just as people complain about Apple hindering innovation with these moves, I think there's something to be said for somebody getting out there and trying out a different model [can "open systems" as a model be a monoculture?] than just putting out a platform and then disclaiming responsibility for how it's used. Not saying the results will necessarily be better, but for somebody to try a different model doesn't seem outrageous in a world where there are many intensely competing platforms. If Apple dominated mobile devices, it'd be much easier for me to see these moves as outrageous. As is, they're one option among many and as a result of their policies their platform has both unique benefits and drawbacks.
