I am genuinely curious - if you were a software developer, and wrote a commercial package, and tried to sell it, but everyone just "shared it" and copied it instead, how would you feel? How would you describe their behavior? What if you were an author, and spent a year writing a book, but instead of buying it from the store, people just made copies of it? Or (in the most relevant example) - you were a production company that invested $50mm into a box-office picture, but everyone decided to share it instead of paying for it? I'm not sure what word you like to use for "People who make copies of other peoples songs, books, movies and software without their permission", but I'm happy to adjust my vocabulary when discussing that behavior with you.
