Damn, the conspiracy theories are real. Deej is a community manager, not a programmer. There is no reason to expect him to understand every facet of how Destiny is put together. I personally believe that xûr's weekly inventories were generated as soon as he was inserted into the game. This is why the devs know what he will be selling, but not necessarily have control over it. This would reconcile the two statements made by Deej, showing that the process was clarified for him when he sat down and asked the guys who wrote the code for xûr. This is not national security we're talking about here; it doesn't have any actual impact on the game whatsoever. People acting like he slipped up and gave out SSN's or something.
