It's irrelevant what the customer wants to use the electricity for. The increase in electric cars is already challenging how we manage our power grids. If it's in demand, charge more.
Lasing out against noise or heat I can understand, but unless electricity is being subsidized, I can't fathom the line of logic people take to justify lashing out against how someone chooses to use electricity they're pay for.
I suspect it's due to irrational hate rather than sound reasoning.
Furthermore, electricity prices do no include environmental externalities. So when you burn so much electricity for things that many people deem wasteful, those people do have reasons to get pissed and yell at you in the internet. Wellcome to modern society!
