This is FUD. As incredible as it seems, MtGox's problems are, in fact, technical. And it was quite a relief to realize this. Also, there is minimal danger of a bank run. MtGox makes a profit off of every transaction. Therefore they control more BTC than users are able to deposit. Hence, since Magical Tux (the owner) is motivated not to go to jail, he will not run off with people's BTC. For anyone who wants the truth,…
What if the technical problems lead to a situation where they are short BTC? Your link mentions they could have double paid people which would lead to that situation. Then there's the issue of seizure which apparently has happened at least once.
Relying on your unlicensed money changer to be fair because "he is motivated to not go to jail" is precarious. Madoff's client's probably said the same thing... That's the beauty of the FDIC and the terrifying part about BTC exchanges.
