Not to mention the fact that oftentimes pirated content is just better. DRM free games run better and some work people have put into remastering media in general is outstanding.

I found a collection of the DBZ anime which is color corrected, proper aspect ratio, higher resolution, improved audio (from a different home release with better audio) made by fans for no profit. Even if you wanted to you couldn't purchase that but piracy made it possible.

Unofficial remasters of some old, poorly mastered songs have made a difference for me and I wouldn't be able to enjoy them without resorting to piracy.
