So in other words, you can't really sell or give away any of your own games with a serial, because as soon as you do this you perform a breach of copyright ? I dunno, seems fishy and non-enforcable to me. Lots of publishers make you agree with outrageous EULA's but that doesn't make those EULA's valid, only the parts that are legally enforcable. And I think he's entitled to give his key away to one person, maybe just not publish it so thousands can use it. Anyway, it's all a bit murky to me, and since the offending article is now removed, we'll just leave at that, ok ?
