There is zero way that sending Apple all MAC addresses on the local network helps with either of those.

  Of course it does. Apple has a database of "MAC address <-> GPS location" pairs. By knowing the MAC address and signal strength of devices around you it can triangulate the position of your device without needing an in-built GPS or celluar modem. It's what allows Macs in particular to know their location in a pretty accurate way.

    Reporting the MAC adress of the router and the current GPS location is all that is required for that (Google does this as well). Reporting the MAC address of all other devices on the network does absolutely nothing to help Apple provice location services and is a massive invasion of privacy that gives them the ability to build a conplete social graph and track the location history of people other than the iPhone owner. The paper states that iPhones do this even when "use of location is disabled" so your attempts to defend this practice on those grounds is completely absurd.
