Well, you know what they say about being too close to something to speak on it objectively. Which in this case means: there's the way these systems were designed to work, and how they actually work toward the end-goal of keeping the systems they secure, secure.

I'll believe that Apple's operating systems are significantly and measurably more secure when they can make it a few years without a maliciously formatted iMessage crashing the kernel. Until then; its arguing minutia. Everyone has security issues. Everyone is taking steps toward improving their security. No one is so far ahead that they're worth white knighting on HackerNews.
