Only in the sense that producing anything as a regulated monopoly is stealing from the consumers of that monopoly good.
People who own solar panels become producers under net-metering. They are just like any other firm in the market. The prices are wonky because they are regulated by law instead of free competition, but the prices of all utilities are wonky because they are regulated by law instead of free competition.
Net metering is a subsidy for upper middle class folks who own their houses and want solar panels because it's hip and cool.
The costs get directly passed onto the other consumers. The poor and middle class.
