Does anyone have a reason for why this wifi mapping invades my privacy? I just can't see what makes it so wrong, I mean I am not ecstatic about my router mac and general area being tied together but is it easy for someone to find where I am based on what wifi I am connected to through a browser? The only time I see it being a problem is if you have malware and they are able to target you by location but depending on what malware you are infected with it might be just as easy for the malware users to look somewhere else for location. Maybe I am just being dense.
