Looks like he sold one of his domains, ww.com, for 3 million; guessing he probably doesn't need donations :)

I'd be interested to know what the HN sentiment is for this kind of behaviour; his only claim to these domains is that he got there first - he obviously has no intention of using them beyond selling to the highest bidder.
Recently I listed an unneeded but above average (trademarkable, keyword, .com) on HN as free to anyone who could use it, with the stipulation that they pass it on if subsequently not used.
I'd be glad to see more of that.
