They missed the point that usage is not part of the fee change. The part they want to make income based is the service charge. So your final bill will be service plus usage.
At least CARE is opt-in, like SNAP benefits, where you necessarily compromise your privacy to demonstrate your low-income status.

"... PG&E, Southern California Edison and San Diego Gas & Electric filed a joint proposal with the state Public Utilities Commission seeking to add a fixed monthly charge for services, based on household income levels.
This fixed-rate plan would reduce monthly bills for low-income customers and if electricity usage is controlled, bills would also be lowered. It would cost as little as $15 a month for low-income households and up to $85 more per month for households making more than $180,000 a year. ..."
