Do Facebook and Apple really have an analytics platform anywhere as good as Google analytics? If one of them acquires kissmetrics or mixpanel of something I'd believe you but having used facebook's business interface first hand it's only good at analytics "on facebook" it tells you very little about your actual site even if you have their pixels on every page. With Google I can see my marketing funnel from on every platform.
