In this instance knowing the difference between value, cost and worth would have been very interesting. Unlike a great deal of pirated IP, where the value in lost revenue to the owner is very low - because it rarely displaces a legitimate sale - this operation clearly did displace a great many legitimate sales of MS products. It wasn't piracy, it was forgery. End users, and it seems at least some of the middlemen, thought they were buying the real thing. But clearly there must have been a discounted price to attract sales away from the legitimate channel.
Piracy doesn't go to the trouble of printing copies of the boxes, faking the holograms, etc etc. It is usually found for a few dollars on a writeable CD at some market stall.
So, there is a very interesting set of questions unanswered in the bland statement of the software's worth. How much money did these guys manage to sell the forgeries for, and what reasonable estimate of lost legitimate sales did MS suffer?
If these guys managed to pocket even a small fraction of the $900M retail value, four years in pokey is a very small price for such riches. Indeed merely a part of the price of doing business. I wonder how many readers would be prepared to do a small stretch if paid, say, a million pounds a year for doing so.
