Think of it in terms of the value of what's being stolen. For example, a songwriter spends perhaps 1000 hours creating a music CD. He then essentially says to you, "If you pay me $15, I will allow you to listen to the music on this CD whenever you want."
The $15 the songwriter doesn't receive because you decided to steal a "counterfeit" copy doesn't make the songwriter's loss any less real.
why bother this argument? you won't/can't win. these threads have existed on various forums for as long as mp3 downloads have been available. probably prior to that.
my take? downloading is easier than getting something legit. it's so easy and quick that a lot of people sometimes go into a frenzy and grab too much stuff. next day they delete it. the content creator hasn't lost anything in that scenario.
just because someone downloads something doesn't mean they were going to buy it legit if they couldn't get it via torrent. on the flip side, some studies say some downloaders buy more legit content than the average person.
who's right? no one. you'll never get either side to agree so it's a pointless task.
