I have two feelings about this. The first is, that if my data usefully supplies information to "the commons" which makes services like maps better for everyone including me, there is a zero-sum win-win here, and I'm ok.

The second is, that if there is some private leveraged advantage Google gets, over other people, which dis-equilibriates in the commons, This is not good, and I should be told quite clearly thats the case, and how it works.
