Google are now in trouble in South Korea for collecting private WiFi data with their street view.

They said it was "accidental" but if you believe that I guess you are eagerly awaiting a visit from Father Christmas accompanied by the tooth fairy?

They are still not out of the woods in the UK either. OK our regulators said they hadn't collected any personally identifiable data, but intercepting private transmissions is a criminal (felony) offence under different legislation...........Scotland Yard are looking into it.
