Who Cares? I still don't see what the big deal is. They are not stealing anything, they are scanning the air and picking up the SSIDs that are easily available that anyone can already see. Keeping track of Wifi locations benefits anyone who pulls up a service that uses that information to help pin point a persons location faster than GPS can normally lock onto a signal.
Making it opt in only would make the service worthless, as most people don't know how, or won't put the effort into applying the map flag. This provides a solution for those few users who are offended or surprised by the fact that the wireless signal goes through walls into public space.
