I actually just had this discussion yesterday at length, en-mass, most day-to-day regular users will not focus on their apps, or even care to check the update status of the OS, in the regard iOS offers more 'out of the box' security and thus overall is a better option.
If you allow any other OS for example, you can't manage the security of that device anymore. So no it's not a false choice. It's just a choice.
