In SkyHook privacy policy [1], there is no information to remove your device Ethernet address from their DB. The FAQ [2] doesn't give more information either. In Google Geolocation Privacy Policy [6] doesn't explain how to opt out your MAC address. Note that often the irony for opting out is that you have to be identified. There are many forms of this type [3] for encouraging people [4] to reveal their location and improve location DBs, I have seen people complaining about their router wrongly located after moving. As for your own laptop data, that might be the reason. And in addition, laptop owners using browsers that take advantage of HTML5 geolocation technologies-- such as Firefox 3.5--are also contributing to the database when they upload their location to services like Twitter or Foursquare or use Firefox geolocation services. When that data gets sent back to Firefox, it shares the location of all MAC addresses in range with its partner Google for mapping purposes. --- [4] W3C GeoLocation API [5] gives this possibility.
