For all they did wrong, known for a very long time, they were the lead chargers in bitcoin and all these exchanges got "real investors" and after Mtgox was successful. If Mtgox were trading magic cards, the story would have been probably different for most exchanges. They deserve to shut down, and stop business. They dont deserve to get ridiculed because they didnt measure up to the expectancy created around an instrument they dealt with when it was worth nothing.
