Don't be so naive. You'll find that any internet content/service provider will have full access to your information/data. Apple would typically receive dozens of requests each day to make a users data available should a user be under criminal investigation for example.
Agencies like GCHQ have pretty much open access to everything (and I do mean literally everything) that passes through the internet anyway, encrypted or not.
sorry was typing that before bed. i meant regular access to your files. there's no reason for Apple to continuously inspect your files, while microsoft, a search company, has a million ways to use your data
