Easy to shout FUD and probably that is what it is.  But do we know the individuals who wrote the code? Isn't there a closed source part? I have a relative who does white collar crime investigation.  The thing that gives it away is shoes.  If someone suddenly sports all new expensive shoes then they might be corrupt.  Always works. The Darkcoin need to think about whose footwear suddenly improved ... do they even actually work together in an office or is it all distributed over the internet?
