If I were to steal cable, I would be using the cable company’s resources to deliver content to my house without paying for it. If I were to set up an inductor under a power line to steal power, I would be depriving the power company of power they could have sold to somebody else without giving them anything in return.
When I torrent something, I don’t even put any additional load on Netflix’s servers. With their current monetization scheme I don’t even make the show’s producers any less money.
