Yes, the publisher can decide how their product is distributed, and with what limitations. However, in this case, it isn't really being distributed... the game is there for maybe an hour, and then it's gone, and the friend decides whether to buy or not. If you physically brought your system over to your friend's house to show of the game, is that still immoral? Or, the slightly easier route, bring your friend to your system to show off the game, is that immoral? How about uninstalling on your system, installing on your friend's, uninstalling on your friend's, then reinstalling on yours? All bring about essentially the same results, and in all situations, Malfador and Shrapnel aren't affected (except perhaps by getting a new buyer). To me, it all just seems like varying numbers of flaming hoops to jump through, when there really is no necessity for any hoops.
