Why shucks! Their company slogan is "Don't be evil",
surely we can trust them (or was it "To Serve Man", I forget).
And now they'll hold all your voicemail for you for free
with the new google voice service, and track your
position for free by following your android phone,
and backup all your files for free through your unsecured
wi-fi access point. Golly! How could anyone be
paranoid about such a wonderful company...
