but the data collection is not on by default (though applications like Maps will prompt for it)
No and no. Not only is the data collection on by default, even if you turn it off some Google apps (e.g. Maps) just don't give a damn.
I recently updated Google Maps on my Android phone (a move I regret). A couple days later I went into town. I checked my phone after I was back home and it suggested I leave reviews for the stores I visited (it listed them). That creeped the heck out of me.
