“such as cutting off your electricity remotely whenever they feel like it”
Only if you don’t pay your bill. And utility companies send out notices long before they turn off a service. If you can’t pay due to a fixed income (social security) or if you have a medical condition that requires an electrical connection (oxygen generator) they do not turn off the service.
These smart meters make it impossible on the otherhand for some deadbeat hoodrat to swipe the meter off one house and put it on his because those meters are coded to each residence.
Actually if you read the fine print on the smart meter policies they do give the authorities to cut off or limit your use of power “during an emergency”.
That could be a storm, a fuel shortage, civil unrest, planet getting too warm, too many people out there watching Fox News....whatever they feel the “emergency” is.
