Sure would be nice if someone would jailbreak the iPhone, so we could have these sorts of options in our little walled-gardens too.
Android apps ask you if you want to update to the new version or stick with the old one indefinitely; privacy settings are non-negotiable. iOS apps ask you as they go: If iOS had an SMS API, Facebook wouldn't need to ask you until you enabled two-factor authentication (assuming that's all they use it for). And you could turn it back off later if you weren't comfortable leaving it on.
On Android it's all or nothing.
