There's a certain comfort, and security, from the anonymity afforded by randomly generated SSIDs.

On of my neighbors SSID used to be some bad words towards people working in IT. I think he got some bad experience with his ISP support.

Mine is "go fuck yourself" so whenever anyone asks what my wifi is, it results in a hilarious exchange.

My parents were 'CIA moble survalance unit'.

Google maps doesn't need to be able to connect to your wifi in order to use it for location detection. i.e. You still need to add _nomap to the ssid.

Google maps cars go around scanning WiFi SSIDs so they can map them to geolocations.
