I know it is pedantic, but “digital piracy” is a non-sensical phrase.
Piracy means “crime on the high seas” and has been extended to mean crime in the air because of a long tradition of naval-aerial military jargon transfer. That crime is almost always theft or acts committed in the process of theft. The gist here is that piracy is theft that happens in transit through ungovernable space. So when we say “digital piracy” we are literally saying “the theft of digital objects while in transit through ungovernable space”. It seems easy enough to equate the Internet with the ocean, even though that is wrong, but it being wrong isn’t why the phrase is non-sense.
Digital things cannot be stolen because theft is the act of depriving someone (the owner) of something (the object). You cannot deprive someone of an infinite resource, and all digital objects are, by their nature, infinite resources since you can make as many perfect replicas of the object as you like and the original remains unaltered.
So, what we mean when we say “digital piracy” is actually the symptomatic consequence of new technology forcing changes to existing business models that were once very profitable because of artificial scarcity manifest through the controlled distribution and supply of physical things. We could say “unauthorized replication” if we wanted to be accurate, but it isn’t flamboyant or evocative in the right way to support those who are saying it to sensationalize their own inability to adapt to change, so we appeal to the cultural image of buccaneers and slap the modern day equivalent of “electro!” in front to show that it is new and noteworthy.
