> it's not clear that my Google Map data is 'mine'

Yep, definitately not clear. But that's why it's a good for courts to start thinking about such things so that principles can emerge out of real-world cases.

My guess is that data-ownership is mostly bunk ("information wants to be free"). But privacy advocates who think in those terms are on to something and "ownership" is just the nearest model we can think of. Over time we can evolve a clearer idea of of what that something is.
