The video is right, however, people willingly volunteer much more info through other forms of the control grid.
E-mail, facebook, cellphone, mail received at your house, mailing lists, electronic banking, credit and debit card usage. I don't have any of these(E-mail to get on here is the wifey's), but I
had the electric company install a smart meter to keep any mofos from coming in my yard. I feel the trade off is worth it.
Anyone growing reefer hooked up to a smart meter deserves to get caught.
