Re: Legal basis
Add another string to that bow, last time I looked, the California Public Utilities Commission was regulating businesses with a (intrastate) presence in this state, whether or not they operate as an interstate business. Not that this matters much. Just the fact that the State of California is declaring which firms they will do business with and no others is our look out not the federal governments.
Indirectly, it'll be just as interesting around how this applies to Verizon's fuckup during our last batch of wildfires.
