I don't think there is any real moral dilemma... (Score 1)

I think people who purchase domain names for the purpose of hijacking them or holding them ransom are greedy, and should be kicked in the head. On the other hand I don't think its appropriate for any organization to prevent anyone from registering any unused domain name. It will be a glorious day when people a mature enough to register domains based on real legitimacy. It seems like your company purchased this domain name for a purpose, and over the years for what ever reason it has become less useful to you... If that is the case, I don't think there is any real moral dilemma over whether or not you should sell it... Hell, auction it off and give it to the highest bidder.
