Isn't the argument here that those mixers were ran by criminals?
It's not the same if some service is used or ran by criminals, but those ''evil'' North Korean hackers are perfect excuse for everything 
Exactly. I completely agree. Now any hack is the fault of this North Korean group. As if there were no more hackers in the world. Well, but while all these events occur, the same culprits always fall on the shoulders of the same people. The real bandits can run away.
