Wow. Where is all of this anger coming from? The guy is putting on a conference, and has done a ton to help bitcoin. He puts in more 'actions' every day then you have put in so far. His show is a service to the bitcoin community.
A seller has the right to price items or services ANY WAY THEY WANT. With the price of bitcoin changing so much it is not unreasonable to price things in USD converted to bitcoin as payment.
Respectfully, you have no idea what I do for BitCoin, so speculation that someone may have done more than I have is just that - speculation. I'm totally fine with you taking that stance though, as the free market will prove the truth in the end.
