I don't want to turn your thread into a big discussion on priacy, and, as they say "others know more", but I do know that one aspect of the piracy problem concerns sellers out there (on eBay and similar places) selling "digital" kits that were only offered by the original publishers as printed kits, meaning that they have been scanned by the seller, PDF'ed, and sold as their own, even if the original publishers still sell the printed kits. Now, obviously I'm not selling anything, but even giving away scans of somebody else's work printed or otherwise, probably isn't too kosher either. So, out of respect for Orlik, I sent the actual unused parts of a kit I paid for.
Do a search here and the other paper model forums on "piracy" and you should get a good idea of the kinds of do's and dont's in regards to copyright and piracy.
