> Bonus points for bogus names like "Starbucks Wifi" or "McDonalds Free Wifi" in the middle of the highway. Is the goal to make Google Maps publish a Starbucks/McDonalds in the middle of the highway? I can't imagine they would use the SSID as a source for building location.
No, the SSIDs are used to assist the GPS on where the user is located. Likewise, the data is used to triangulate a user in a specific business/location without needing access to GPS (some more nefarious uses: user is connected to "Joe's Psychiatry Wifi" every Wednesday, maybe we could group the user as a depressed adult for advertisers).
If you can think of any kind of nefarious use for data, you can safely bet that Zuckerberg has already done it: https://web.archive.org/web/20160830031017/http://fusion.net...
