You are not seriously suggesting that an old forum member faked the heist in order to crash the price? Are you?  

That wouldn't even make any sense.  The fact that a hacker can steal a plaintext wallet.dat is not exactly a secret. This vulnerability has been discussed ad nauseum on this forum and consensus was reached months ago, that it is a good idea to keep a separate savings wallet. Even allinvain admitted that he knew his setup was highly unsafe before his coins were stolen.

The heist revealed nothing that wasn't already known, besides it's not a bitcoin vulnerability but an OS vulnerability.  Thus the market should ignore such news ... unless ... the market is dominated by ignorant, immature amateurs who don't understand bitcoin and are swayed by whatever they read on Gawker.
