I think the problem people have with Gox is the way they handled the announcement and also the havoc it caused in the Bitcoin markets afterwards which could have been avoided. Their long-winded announcement went into a lot of technical detail about the transaction malleability flaw. Most traders are non-technical users of Bitcoin and would assume after reading the announcement that Bitcoin was broken. Sure enough, the announcement caused the flash crashes only minutes after release at Btc-e and Bitfinex resulting in millions of dollar losses from panic and margin calls.

This resulting panic in the markets could have been easily avoided had the announcement been reworded differently in a less dramatic fashion. You only need to read the first 2 paragraphs and immediately you suspect some serious flaw in Bitcoin. Less emphasis should have been made on all the details of the flaw, we are not to blame, more emphasis on that Bitcoin is not broken, this issue is not major, everyones funds are safe, we apologize to our customers for long delays etc... The devs were right to say that Bitcoin is not broken in order to prevent FUD from spreading and reaching the mainstream media with damaging articles where average joes would use this as another reason to avoid Bitcoin. Thanks to the devs a lot of the articles out there emphasize that this is a minor flaw and solutions can be easily implemented.

Mark Karpeles may understand technical issues well, but when it comes understanding investor and traders psychology and the huge impact these announcements will have on the Bitcoin markets, he either doesn't seem to have a clue or simply doesn't care (negligence).
