Some people here like iOS for the reasons you described. However I'm willing to bet, unless you can show me otherwise, that it's a vocal minority. I don't know of anyone personally who is happy that Apple disallows GPL code.
Comparing Apple's digital Fort Knox with Google's unsupervised free-for-all is a false dichotomy.
There exists a happy medium, where power users get all the freedom they want but apps are still by default beholden to certain restrictions. And this is orthogonal to a proprietary API.
