Although ads are a bit annoying, I don't see any reason why a few street view adds are a bad thing. However...
â€The user profile may store information such as, for example, previous searches conducted by the user, websites visited by the user, the location of the user, and demographic information about the user. When the user chooses to view a photographic image of a geolocation, advertisement module may utilize the userâ€™s profile to retrieve a targeted advertisement.â€
I always hate being reminded that I'm being spied on.
