Piracy is on the increase - and it will never be stopped because it is human nature - to get something for nothing.
The Internet's major plus point is also its major minus point - it is not policed, which allows true freedom of speech - and piracy.
Speaking as an 'older generation' AB'er, i can confirm that the debate about music 'piracy' has raged for thirty years, with no signs of abating.
In its early days, the debate was about home taping - the record companies bleating that it denied them / their artists income for their work. Statistic proved that the vast majority of people who taped a friend's album bought an original copy for themselves, thus neatly nixing that argument.
Now, with the net and downloads, people simply accept 'free' music as a right, and that will never change. Again, the upside is that millions of musicians have a platform for their work - and may have to compromise on financial rewards in order to use the system.
The only hope that the 'industry' has is to clamp down on people who are making vast profits from illegal file-sharing, and that is a difficult battle, with the abikity of 'pirates' to fold up their tents and steal away into cyber-space, to set up elsewhere ten minutes later.
In conclusion - should the net be policed? Probably - but by who?
Will piracy of music ever be stopped - no, which is a good and a bad thing, largely depending on whether you are a musician or a fan.
