If you believe Assange, Domscheit-Berg was working with international intelligence agencies.
If you believe Domscheit-Berg, Assange failed to provide sufficient protections to the leakers of the documents, which included the Bank of America scandal that was never released.
I tend to lean with Domscheit-Berg, in that Assange may have become blinded by his anger and eagerness to release the documents-- remember how he touted them left and right?-- but it's very possible Assange is correct.
Or, they may both be right. Either way, we've lost a treasure of information.
