Although both are American companies operating under the same rules, there is a fundamental difference between Apple and Google's business models.
Apple makes its money from selling you new hardware every year or two - they need to make you lust after slick, shiny things every keynote.
Google makes its money from knowing about you, mining that data and converting that into advertising clicks - they need to collect as much information about you as possible.
Which means that the same pieces of data have different value to the two companies.
(Of course, Facebook follows a similar model to Google)
