@Wayne:
We are now entering a very gray area where you are technically breaking the license, but are morally still in the clear. Or rather, not as tarnished as to say you've done something Despicably Evil. Take the OS4 example. I wouldn't call it piracy, on the conditions that you payed for the original, keep the 'cracked' OS4 to yourself, and don't use the original and patch side by side for extended periods of time, unless you have more licences. (A practical definition would be 'no longer than 15 minutes a day', for example.)
It's like the no-CD patches for games. *All* of my (PC) games are originals. At one point in time, I upgraded my CD-ROM drive only to discover that about half of those games would not work any longer because the drive couldn't handle the copy protection mechanisms. If I were to apply your method of reasoning, I would have to stop playing the games, and complain very loudly and bitterly to the manufacturer until they released new firmware, or keep exchanging drives until I find one which works. It is unlikely that a big company will release a software update just to please me, and computer stores don't like customers returning products in rapid succession. (I know of a store which would 'test' the drive, conclude there is nothing wrong with it, and deny me the refund.) So I used a 'no CD' crack in order to play the games. Are you now going to report me to the authorities for software piracy? (Truth be told, I discovered that the drive was truly broken, so I was able to get a proper refund, and buy a new one. I discontinued use of the cracks after I found out the new drive handled the protections flawlessly.)
