What's wrong with that? Does number of games determine your eligibility for giveaways now? He's probably spent more on Steam than a lot of us if he has 1400 games. The giveaway was open to everyone, he managed to get the code. I don't see the issue.
Would be interested in this too. This plus the Kingdoms of Amalur sale... if Amazon has a deal on Anno 2070 at some point I think I'll have got just about every game I wanted when the sales started!
