You don't need to be the titular head of an agency/department/service/whatever to be the defacto head.

I'm not really sure how that's relevant? I'm not even American, I don't care who runs it. This seems like pointless flame bait.

I think the ubiquity of general disarray and confusion surrounding this agency is relevant to the discussion of whether or not we can trust their intentions and claims. So, further evidence of the extent of this general disarray and confusion is worth considering and not "pointless flame bait".
