Apple spies too. Their core business model just isn't based on selling that data. Apple knows every single app you've installed on your phone, the version, the time you installed it, every update you've ever had, how often you check for updates, the apps you removed, and probably much more. You MUST login to an Apple account to have an anyway usable iPhone. Android, if you don't login to Google, and use a more ethical app store, get's much less data. Obvious disclaimer: The entire of iOS, and parts of Android factory builds are closed source (e.g. the bootloaders), so we can't really know for sure what more they collect.
