Apple does this too. They just bury it 4 or 5 system levels deep before you can see that they track you everywhere and recognize your home, work, and other frequently visited locations.
I have no proof that it is being used for advertising, but they do still have a copy of everything. Who's to know what their future thoughts about advertising will be. It's their Frequent Locations feature.
On iOS, location tracking is configurable per-app, at least. I can deny the Weather app the use of my location data while allowing the Camera app to access it.
Do you have any proof that Apple uses this information for advertising purposes? Their privacy statements say otherwise. This would be a huge deal.
