Microsoft's undocumented function calls gave a massive increase in performance, making competing applications in multiple domains essentially uncompetitive on the platform. Apple is hiding a minor piece of functionality that can be implemented in another way and, indeed, has. I find many of Apple's iOS business practices abhorrent, but trying to even suggest they are in the same league as 80's and 90's MS is an insult to all the companies MS destroyed in those decades.
