Is this really a flaw in bitcoin? And I do not agree that this makes bitcoin any less anonymous. There is still the gap between key and owner that needs to be bridged before identification can take place, and I do not believe that the word anonymous guarantees no history available, only that the history cannot be linked to a person. By definition, I mean to say. I would compare this to a headline titled "bitcoin is less secure" because of the Mt.Gox hack. Similarly not the fault of bitcoin.
