Saying that malleability is an issue is no different than saying that buggy code is an issue. It's an issue if you let it become an issue.
There is a million ways to fuck something up no matter how many rules you put into place. Besides, at what point do rules become something that are meant to be broken.
The simple fact is that GOX either mistakenly or purposely ran buggy code that allowed some people to get rich at the expense of some unlucky bag-holders.
Instead of talking about malleability issues people should be asking where the fuck is my money period.

A minor nit but transaction malleability was not a bug; it was a documented yet debatably undesirable feature of the Bitcoin design. I can't really argue with the rest of it.

Anyone that has written software knows that there can be a fine line between bugs and features. It all comes down to whether you let it exist or not.
