I really thought that "piracy" comment was a tongue-in-cheek joke (so I had laughed and played along). I'm sorry if I had offended someone.

As for what it is - I believe I clearly wrote that it's called copyright infringement (or license violation, or unlicensed use, or unauthorized copying if you want different wording). And a person is violator, perpetrator, unauthorized user or something like that (I'm neither a lawyer, nor a native speaker, I bet one would be able to come with lots of correct terms)
