Zero cost of electricity if that's illegal is not right, I mean stealing is bad right and by the law you will be punished just like the recent cases about grandma stealing power, so that can't be taken into consideration.
Yes, this is wrong, but it happens. Therefore, this should be taken into account.
But someday it should end. Even in Russia, where mining was almost not regulated by banks, there was a case when a bank requested a wallet address and confirmation of payment for electricity.
Well that's kinda messed up when a Bank or even worse government requesting a wallet address just for electricity bill, It's like they knew everything.
However, zero cost of electricity could from an alternate renewable energy and that's by any means not stealing. well, I guess i'm agree with your statement that whether that's illegal or legal shall be taken into consideration because they just happened.
