If you're dumb enough to have an unsecured network in the first place, then you only have yourself to blame if ANYONE (Google, a neighbor, etc) gets access.
End of quote
That's like saying if you park your car in a public place you're asking for it to be stolen. Simply put, Google has NO right to steal wi-fi information just because people haven't or don't know how to secure their networks.
My neighbours leave out their milk money (home deliveries) once a week.... just because it's there and I know it, is not an invitation for me (or anyone else) to takel it. That's the trouble with Google, though... it lays claim to everything it sees, knows is there)... and justifies the data theft by saying it is providing a service (with that stolen information).
Mobsters provide a 'service', too - be it protection, drugs, booze, women - but it don't mean you wanna do business with them. Google might wear the corporate cloak, though it ain't Zorro underneath the mask, but rather another bandit. And how does Google keep getting away with it?? Friends in high places, perhaps....maybe a bit of unofficial official snooping in exchange for an official blind eye?
In any event, I've come to learn that you don't trust anybody who constantly says "trust me"... nor anyone who says "don't be evil", cos inevitably they're doing it themselves and don't want the competition.
