Your smart meter is very secure (against you) and very insecure (against hackers)

Odd. Did your power company make you buy your own electric meter? PG&E owns mine. They also own my gas meter. My water company owns my water meter. Heck, the city owns my trash cans.

Why would the power company be regulating how you use power? Smart meters are so the power company can do time-based pricing for consumption or generation of power. As far as I know, they have nothing to do with the power company regulating how you use power.
