There is no defense for PG&E for the Camp Fire. This is an organization that is notorious for under-maintaining its assets. Its state of repair is so shoddy that it regularly turns off power for many days at a time ("public safety power shutoffs") to huge swathes of its service area. No other comparable utility does this - not San Diego Gas and Electric, not the Victoria Electricity Cooperative (Australian utility), no one, because they have entered the 21st century and don't need to resort to crude hacks like shutting off all power to prevent fires.
The proof is in the thread. Barely 10 years ago, PG&E pleaded guilty to another felony, when its under-maintained gas pipeline in San Bruno exploded, killed 8 people, and leveled a neighborhood. That utility has a cultural problem going to the very top that prioritizes profit over safety, and I sincerely hope it emerges from bankruptcy reformed.
