That doesn't make it any easier for people who have iPhones but can't install your app because your app is incompatible with whatever Apple demands. Trust me, most people who buy iPhones are completely oblivious to the app store rules and review process.
That's irrelevant. Both iPhone users and app developers have options on both sides. Developers can ignore Apple's platform and end-users have lots of options for phones that aren't iPhones.
