Jerry Brown and Gavin Newsom are the top of the chain for PG&E. The The California Public Utilities Commission which is appointed by the Governor controls PG&E.
CPUC sets the regulations. PG&E finds the easiest way to maximize profits under those regulations. Sometimes those profits are maximized by by just dumping the hexavalent chromium rust inhibitor into the ground.[0] Other times by delaying maintenance on 100 year old towers.[1] Even executive personal profits can be maximized by diverting safety operations funds for executive bonuses.
