Note that PG&E is being held liable under current law for fires started at the site of it's equipment. Regardless of whether or not PG&E was at fault due to lack of maintenance. So when PG&E is found liable then the public and media often conflate it with being at fault. Two different things.
Note that SB 901, the recent PGE bailout over last year's fires (Coffee Park, etc.), is illegally being applied retroactively to this year's fires (see George Avalos' article in the Mercury). It doesn't even take effect (legally) until 2019.
I feel like your statement is misleading. Regulators have come out and said they don't want PG&E to go bankrupt. PG&E and the regulators are probably both supportive of extending the existing legislation to cover 2018.
However I am not aware of PG&E or regulators having acted illegally. Publicly stating an opinion before taking action is not illegal.
Plus the bailouts are generally being used to fund PG&E's rebuild on fires where they weren't at fault (from a common sense perspective) but were found liable under California law (see my earlier statement).
People are angry and want someone to blame even tho this was a natural disaster. With current laws, PG&E is being painted as the bad guy and are stuck between a rock and a hard place.
