I've been of the opinion that
piracy is not applicable to the unauthorized copying of software. A
copyright violation or perhaps a
breach of contract, yes.
Piracy is a
rube-word used to make it sound worse than it is.
That said, there is empirical evidence that people who can buy, do. People who can't, copy. The only threat is from those who can by, but are such unprincipled bastards that they copy anyway.
