James, you are exactly right. Microsoft, for example, relentlessly shuts down auctions for Microsoft software (as the rights owner, Ebay gives them the authority to end auctions).
I`ve has personal experience with this. Way back in the beginning, when I was still trying to figure out what to sell on Ebay, I was at a flea market one day and came across a brand new, unopened, fully retail licensed copy of Office 2003. The seller wanted $5.00, but I`m an Ebayer, so I bought it for $2.00.
Much to my dismay, within hours of posting the auction, Microsoft took it down. I actually had to take pictures of the box`s UPC code, and open the box and take pictures of the COA, and send them to Microsoft, who then relented and allowed the auction to continue. I think it sold for $200.00 - my best ROI ever!
