hello ...
piracy is a serious concern, it may never be eradicated, but i'm sure that the real problem is elsewhere. i'll comment according to personal experience in my country, it can certainly vary from your experience...
1 - people pirate because it is an existing option, we had (now they are being killed by government) a lot of DVD/VCD shops selling only copies of movies & games, they were making a lot of money & were tax payers (like prostitutes too

)
since law enforcement, they were tracked down & now we have less of these around the island but with the internet more people have access to pirated contents, except for torrents being killed slowly on the net.
the best example would be about games, in the PS2 days, almost everyone had a MODded console & PS2 games were selling for the just twice the price of a DVD-R, same for PC/Xbox games. This gen we've seen a boost of Xbox360/WII pirated games, yet for PC it dropped a little for the machine cost more to build.
the surprise came from the PS3 side, the game sale was still high, so what can we deduce .... people buy what they want & like, but depend on the supply chain, if they have choices they would go for cheaper solutions, even if immoral or illegal.
I have a lot of PC games i got fro free off the net via sweepstakes, on unsold magazine for Rs 60 (less than 2 US$), via the steamy site during holiday sales & weekly promos ... so yes these game cost as much as pirated ones in my country so that's why i have original, somewhat dated but original cheap games, but i have worth 1200 US$ of PS3 games whether it be disc based, collector's edition or PSN ones. yes i may be of the rare who do not go for piracy, but i believe that if it didn't exist, people would still be buying whatever they like.
2 - piracy exist because of hypocrites, we have some shops closed down because selling unauthorized copies while the ones that belong to some big head nephew would still prevail.
hackers say they would crack software for educational purposes & they do not condone piracy - yeah 'mon oeil' ... most hackers are young, around 17 - 30 years old, so if i don't doubt their genius mind, i do about their maturity. Like all kids, they don't measure the consequences of their act!
i'm not asking them to stop hacking, but if they were mature just say they did but don't publish anything, no they need to be accounted for cracking this or that & need to prove the world they did it - so lame!
3 - Bad products & deception - how can hollywood / activision (taking random example here LOL!) or any singer believe that all their products are worth the 'price' - give us a really good product that's worth it & you'll see a decrease in piracy.
i also see a bad delivery of such product. if movies are released to theaters only 6 moths before being available on other media, make it a different experience, not the same we'll have when going on the smaller screens, maybe with more incentive like, you buy a cinema ticket you get a lottery that can lead to a discount when you purchase the DVD or blu-ray coming out. not everyone will win, but most will hope so & it helps...
now when we purchase a DVD or Blu-ray it already comes with more features (discount codes / bonus contents / alternate endings / soundtracks etc ...) so they already have enough good stuffs for the collectors but what about the simple movie watchers ... thank god we have digital delivery, but this isn't easy for everyone & mostly unavailable to all regions.
movie piracy in MU is mostly because of availability of copies & unavailability of legal content. we don't have netflix/ hulu / etc,,, in our region - why !? but yes, pirated download site doesn't care who you are & where you are!
our VOD service is limited & even if some did find the use of proxies OK, it's still too slow & hard for the mass populace ...
music piracy has changed, before everything was copied, even local artists. then after a big campaign & a slight price drop, we can see people going mostly for the originals, they are even proud of owning legal DVDs or CDs, but no one represent the international artists, sales have dropped on disc since downloading remains best choice - still most people nowadays go for free to play sites - so no illegal download yet no purchase!
sorry this post is too long, will just end here then, piracy is bad! i'm so happy to see so many people commenting on this here, as a future developer it gives me hope, thank you for that....
i hope someday everyone will just see the harm done, mostly to indy & small developers, big ones will survive always!
cheers!
