Google actually does collect wifi location data via Android devices. There's a setting that allows you to toggle this data on/off. If you turn it off, it actually disables the course location API available to Android apps (I recently encountered errors with both the Lux and the UCCW Android applications due to the fact that I had this setting disabled and those apps only had course-location built-in).

Now whether Android actually uses the wifi data to determine location, as opposed to simply collecting it and manually disabling course-location if you don't send them wifi data, I have no idea. It does seem to be related though to the new Geofencing API available in the latest versions of Android.
