Well, it depends on how you look at it.
Personally, I think that once you buy something (music or software), you should be able to share or copy it, or whatever.
Regardless, I doubt file sharing will ever be stopped. Because hey, most people aren't going to pay for something they can get for free.
Also, as is the case with alot of people, some people would never buy (because of finacial reasons, or whatever) the songs/software they download. Hence, the industry isn't actually losing money....at least not on those people.
But then again, you have to consider, why bother to produce something if you're not gonna get paid for it (other than for the enjoyment of it)?
It's a double edged sword.
All in all though, I'm a strong believer in FREEDOM! So that wins out for me. In other words.....I think it's ok
