More privacy issues, this time concerning real-time location:
To provide location-based services on Apple products, Apple and our partners and licensees may collect, use, and share precise location data, including the real-time geographic location of your Apple computer or device. This location data is collected anonymously in a form that does not personally identify you and is used by Apple and our partners and licensees to provide and improve location-based products and services. For example, we may share geographic location with application providers when you opt in to their location services.
You have some control over sharing location data with 3rd party apps in Settings..but it isn't clear if that stops Apple from using the data themselves.
