So this, in your opinion, causes more damage than violating someone's copyrights? This is quite literally just using a resource than would otherwise be wasted. Of course, the electricity use is lower if less people use this network, but this is negligible.
>just using a resource than would otherwise be wasted
I take care with this line of reasoning. It could be extended to a college class with an extra seat at the back, a chairlift at a ski resort on a slow day, that kind of thing. Using either can lead to theft of services charges.
Oh, it absolutely can lead to charges (same as piracy referred to in the comment I responded to), which doesn't change the fact that it is using a resource that would otherwise be wasted. A college class is a perfect example. Not every illegal act is unethical.
