I agree that Apple make it so that unless you use their frameworks then you can't use certain functionalities of the OS, but that has nothing to do with being "lower" or "higher". It's just that Apple has a specific abstraction that you must use in order to access those features. It could just as easily be the other way around and have it so that only web apps can access those features and so-called "native" apps cannot. It just has nothing to do with the level of abstraction.

If you wrote pure machine code without system calls you can't even read a file. You have to call into the kernel, which could even be written in javascript, in order to do that.
