Clarification:
I support downloading music for one reason: I have already been charged, found guilty, and sentenced for piracy--all without ever seeing a cop or a judge.
Every time I've purchased a blank CDROM, I've
paid a fee to the RIAA. I've purchased litterally hundreds of CDROMs for backup up my data files and I've paid the RIAA for the privilege. That's why I have no problem pirating music.
However, I don't listen to much music, and what I do listen to, I support the artist by buying it. I bought the last (double) album by the RHCP. I also listen to meditation music, which I also purchase.
Keep in mind that the RIAA are also the same fuckers that tried to get a law passed (via politicians they've purchased) that would have put repeat down-loaders in jail for 10 years. There are murderers that have received shorter sentences.
As for the downloading of that book. It's neither moral or legal. However, the idea that each download results in lost money for the copyright holder is a fallacy perpetrated by the RIAA and MPAA. In addition to the idea that piracy is theft. It's copyright infringement, not theft. No one has been deprived of a possession.
As for movies, I use Netflix and Redbox to meet my needs. I also like to go to the movie theaters. I go once or twice a month. Sometimes more.
Again, the mentality of the corporations moves me to not care one whit that people pirate their content. Corporations have damaged society with the perversion of copyright law. I have no sympathy for them.
Disclosure: I work in two fields that are open to piracy.
