For example, today BSA uses provisions of the Digital Millenium Copyright Act to enlist the assitance of ISPs in shutting down pirate sites and stopping infringing activity. We got all the books etc. BSA makes a lot of purchases from these vendors and the great majority of it proves to be pirated. The same person who would never go into a store, take a box of software off the shelf and walk out with it under their coat doesn't always see that downloading that program from a pirate web site is essentially the same thing. Those agreements vary.
Some licenses are non-transferrable.
If you have a question, contact the publisher. We are working with other sites. Counterfeiting operations and other forms of retail piracy remain a major area of concern. But increasingly, we find ourselves focusing on Internet piracy. In the past few years we have filed major actions against individuals trafficing in pirated software in IRC channels and auctions sites.
