Not to worry. Pretty soon there will be no more record labels and no more music to buy as the piracy puts everyone out of business. And I hope everyone that cheers on piracy remembers this. I also hope that when they complain that there's no good music being put out, that one of the primary reasons is that you're stealing the stuff that you consider good, so they can only support the stuff that makes money. The stuff you don't steal.
If someone steals from a store, the police come and put them in jail. If we don't afford IP businesses the same protection from theft, then how can we expect to keep IP? It's true these people should not be sued. But they should go to jail just as if they were to steal anything else. It affects us all because the billions a year lost from music piracy affects the entire economy. Only when someone steal music and puts it on an online file sharing, they aren't simply doing the damage of one unit, they are redistributing it and causing the loss of much greater sales.
Maybe suing people isn't the greatest thing to do. But until the law decides to help out by enforcing the law and throwing thieves in jail, there is nothing else the labels can do to protect themselves from being stolen out of business. Luckily a lot of courts seem to understand this. They know that the case of the RIAA is not the same as other issues that would be laughed out of court.
