Define spying? Most of Apple's services are opt-in as opposed to opt-out. iTunes and Siri are where most the data collection happens. In OS you also have device location services, map data collection but most points are easily controlled.
Well, the innocent definition is to keep watch over and the sinister definition requires hostile intent. Either way, it can be considered spying. The problem is that the innocent spying today can easily turn into hostile spying tomorrow, with little or no notice.
