There's still a huge elephant in the room. How are we supposed to trust Apple, Microsoft or any other tech company when it emerged that they fully cooperated with the NSA and their PRISM program. We have to just assume that's still running. Businesses could keep a lot of secrets from us and they're not transparent or accountable to the public.
A good stack of Apple's ecosystem is fully encrypted, so that Apple can't give anything to the authorities. For example: Apple Maps retrieves routes in segments, with changing identifiers. Apple can't figure out where you navigated to.
