The notion that all news is good news can certainly apply here. Bitcoin itself is still growing and as the system shakes out the flaws (or would-be bugs) each step made is going to make it more robust. So here we are, another quasi-crisis and I can certainly see how strengthening the network against the sort of DoS nonsense is going to make it come out better than when it went in.

Plus, add on being able to use the bad publicity to increase the number of people who know about it.
