It was based on some reports (or podcast? I can't remember) that the California government didn't allow the insurers to sufficiently increase their premiums in the burnt areas. The government (or the insurers) cited two reasons: there was a rule that the annual increase should be no more than 7%, and that if they want to make an exception then the insurers must increase the premiums for all the insured areas instead of setting the price by risk. As a result, the insurers stopped insurance renewal for about 60% of the burnt properties. I assume the intention is to protect the insured or to ensure certain equity, hence the use of the term "ideology". FWIW, it thought it was a neutral term, implying that it's a strongly held fundamental belief.
