A source close to Google says that Google has changed how it processes location requests, thus limited the sharing of locations of mobile devices. CNET reported on such sharing earlier in June. Exactly what has changed is not clear, but CNET reports it's seen a change.
Out of approximately 3,000 MAC addresses that CNET tested over the last few days, not one delivered a location from Google's database. Before June 15, Google's database showed them as appearing in locations as varied as [the U.S., China].
