Is this really a thing? WTF? I feel very ashamed, as someone who works in IT, everytime this happens. I mean, people can opt-out, of course - but, in order to do that, they need to know what an SSID is, and how to change it. What about people who don't? Will we just assume that they don't care or that their opinion doesn't matter?
I guess you have a better suggestion, and am curious to hear about it.
Using SSID naming conventions to do this is just dishonest: most of the people who will be scanned won't know what an SSID is. Even if they do, and do have the competence to change it, how many of them will know about this convention? More than this: how many "home network owners" know that their networks are being scanned and georeferenced? This opt-out scheme is ridiculous and plain "hand-washing" - they obviously don't expect people to use it.
