I don't have a dog in this fight and I'm not interested in an extended debate... but I don't think most of Mt Gox's customers realized that by letting Mt Gox hold their money they were effectively investing in a high-risk venture under extremely unfavorable terms.
That's their problem, it's a currency exchange, trading is a risky business, giving your money to strangers shouldn't be taken lightly and you shouldn't just presume it's safe. The Gox problems were not a secret, 10 seconds of research would have informed anyone of them.
Or to put it another way, if people properly understood (i) the nature of counterparty risk, and (ii)how the average Bitcoin exchange handled transactions, suddenly those banking fees would seem like an absolute bargain.
Comity! I don't have a dog in the fight either, and I agree that expectations alignment and transparency are key, and that it is likely that neither were present here.
