The sad fact is that piracy is only getting worse. Even when you can get a song for 99 cents with no DRM or restrictions, music piracy is still rampant. I'm waiting for the next set of excuses.
In '99, it was because music was too expensive and the artists were getting screwed (which is a funny excuse, because 1% of something is something, but 1% of 0 is 0). Later, it was because DRM made it too difficult to play music. This is why you don't negociate with criminals. They will just keep bleeding you dry. The music industry is learning this lesson at the expense of their profits.
Now there is a new generation of kids that feel entitled to music, software, and movies for free.
This is one of the main reasons why I no longer sell applications. I have converted them all to services. This way, there is no way someone can pirate it.
