Pirating, in my opinion, forces movie, application and game developers to create better products. They see all these people are pirating because to be honest the crap is not worth our money. Who wants to pay 10 dollars to see a shitty movie in the theater when you can see it a week after it comes out on your computer for free?
I will buy a movie or game if it is very well done. They deserve my money in this case. Other times, definitely not. Also, most applications are free anyway, but for the pay apps, IMO they are WAY too overpriced.
I've pirated, i've been caught, I haven't changed my ways. But i'm a casual one. No release groups or anything =P.
Oh, and by the way, there have been numerous studies into the 'losses' of these companies, and there has been minimal losses over the years, and still huge sale numbers near holidays (as expected). The music industry especially is a huge lot of whiners. As a whole they've lost almost no revenue. And it still makes huge killings off horrible copycat bands and artists who have no talent and shouldn't be musicians anyway.
Blah Blah. I have to run to class now, enjoy your whining.
