You don't seem to have gotten the implication from previous responses, so
I'll be explicit about it:
The word "piracy" does not accurately describe the effect of copyright
infringement. That use of the word "piracy" is propaganda from publishing
corporations. Piracy, or attacking a ship, is a horrible crime; theft occurs,
and in most cases any who dare to resist are murdered. Real-life pirates are
no better than any other organized criminals.
The word "piracy" seeks to suggest that copyright infringement is equivalent
to theft. Sometimes, people even say this explicitly. But copyright
infringement is not theft; not legally, and not in any other sense. Copyright
is a legal monopoly. Copyright infringement is illegal competition.
Also, copyright is not a right. It's an industrial regulation from a few
centuries ago. Its intention was to impose a restriction on the publishers
wielded by the authors to encourage the authoring of more works (mostly
books). It functions differently now: it's a restriction of the general
public wielded by the publishers in the name of the authors. That is unjust.
