Nah dude, someone took the opportunity to use a slogan originating in witch hunts of people threatening the ruling class in their bleeding of post-war prosperity in America.

This is about some despot using their resources to interfere with what modest self-governance we have in America

From what it sounds like, the safety is in the device not the grid. In case you haven’t noticed, there is a far lesser sense of personal responsibility to those around you in the US than Europe and I don’t know that I’d trust that nobody over here would fudge some bypass to power their house in an outage

The problem with that is the rich still get to enjoy it and the rich live in excess. It would make more sense although logistically nonsensical to keep the price the same but only the poorest are allowed access to it
