Forgive me, but I'm thoroughly confused. What objection is brought up here to Greenwald's work? That he's using the noun "program" instead of the noun "document" when discussing the program that the document entails? That Greenwald's tone is not sufficiently interrogative and peppered with "claims" and "alleges" and "supposes"?

There's no substantive difference between "It was followed by Yahoo in 2008" and "The document claims it was followed by Yahoo in 2008." The furor of the past 72 hours has given no reason to question the document's authenticity nor the existence of the program the document entails. The president himself has alluded to the existence of the PRISM program and attempted to assure us all that it was only to keep an eye on foreigners and not citizens.
