It's not that BitCoin is unreliable, it's that it is still a currency in its infancy. It cannot be used to value things on its own, yet. No matter how much Bruce would like to have a set price in BTC that stays from the start of ticket sales to the end, it won't change the fact that there is still a good deal of volatility in the value of bitcoins. Volatility = a huge amount of risk when you are talking about playing with money you are borrowing (which is essentially what is happening when you accept payments up front for expenses in the future).
You keep saying how Bruce has malicious intentions to mislead and speculate, when that simply isn't true. Now, you seem to have backed down to a statement regarding the volatility of Bitcoins, which I think everyone here can agree with. Just don't blame Bruce for Bitcoin's volatility.
And yes, I agree, the media probably will latch on to the fact that most things for the conference are being paid for in USD. So? Is there anything that could be done about that? Not really...
