The technology giants that were implicated in the NSA/data mining bombshell have so vigorously denied any acknowledgment of the program that The Washington Post has had to quietly pull back its claim that the major firms were complicit in the snooping. In the original version of the Post story that went up on Thursday, the paper claimed that nine companies mentioned by name in the report "participate knowingly" in the widespread collection of data from their servers.
Reporters Barton Gellman and Laura Poitras did write that "several" of the companies they reached out to before publication had denied knowledge of the program, but that did not cause them leave out that assertion at publication. Once the story broke, however, the companies went on the defensive, issuing very public denials that they were in on the plan. The denials were so stout that the paper seems to have walked back that small, but important aspect of the story. It appears the phrase "participate knowingly" has been removed from the piece and an explanatory paragraph added in that subtly acknowledges it may have been the result of a misunderstanding. There are no notes or indications on the Post website that the story had been altered.
