The Hysteria Over Google's Wi-Fi Scanning

IMO, Google put itself in a bad position having this data, whether they intended it or not, because other people can get to this data, by subpoena, thinly veiled threats with law enforcement (in countries where the state doesn't get checked and balanced that much), or plain economic espionage (for all the mobsters out there). It's a little bit like creating an atomic bomb in your backyard: even when you're not planning to do any evil with it, it's still a bad idea to have one because the others will come and want.
Using the magic words "expectation of privacy". If we assume that the general public is clueless about computers and thus many people expect that their open wi-fi is private (even though technically it isn't), then there's a problem. Also see the debate about thermal camera scanning of homes.
...my laptop wifi is going to ask permission to the open wifi...
But that's not what Google did; they were sniffing traffic without associating, so the APs had no opportunity to deny access.
The answer is: you can't. If you can't prove someone did something, it's dumb to make it illegal.

Unless Google was matching the Wifi data with their server traffic?
