There's a lot of fingerpointing but as Daniel Swain put it: 1. This was completely expected and forecasted both short and long term by regional climate and weather experts. Two very wet winters caused fuel buildup followed by an extremely hot and dry year. 2. There is very little that can be done in these situations. 100 mph gusts of embers can't be fought with hoses and air attack isn't possible in high winds. 3. Hard to believe but it could have been a lot worse. Daniel Swain points out there could have been several more major fires like the two big ones but they got put out quickly before they spread. 4. California's climate has likely been this way for millions of years, long before human habitation.
