Well, clearly, the folks involved have not bothered to "run a simulation" to have predicted the situation where someone has made money out of nothing. He didn't "mine" it, he didn't invest it, he didn't exchange goods or services for it. He merely exploited an unforeseen complexity to his benefit and everyone else's detriment. And that's the core reason this rubs people the wrong way: it smells like financial shenanigans. We don't like it when people do that stuff in real life, and we don't like it when it happens in a "funny-money" system that deigns to become serious. The good news is that (as far as I can tell) no serious real money has been poured into or out of this system. If it has, the money was hopefully treated as a highly speculative investment-- thrill money if you like. Not counting Watt-hours and personal time as money, obviously.
