Re the dividends part, that's an issue on which our present society will have to work more and more, because afaik most of those dividends go into the coffers of pension funds/insurance companies/big institutional investors which by their very nature "trickle down" that money mostly to people aged over 45 or 50. Most of those reinvestments you mention will get their financial return in 20-30 years' time, by which point the age-group I mentioned earlier (the over 45-50) will either be dead or to old too care that much about it.
Let's hope they don't do it "the South African way".

Dividends have been very substantial, and evidently outcompeted maintenance. The lawsuits will collect more data in discovery.
Make no mistake, the outage and the threat are attempts at coercion, trying to force California to indemnify them, for free, against their own very deliberate negligence.
If PGE does not want to be a public utility anymore, California should confiscate their assets and turn them over to someone who does.
Now that climate change is creating conditions for the already wildfire-prone landscape of California to suffer more frequent and severe events, the power companies are washing their hands of it. Short of some major state or federal investment in upgrading energy infrastructure (like the green new deal), I wouldn’t expect that to change.
