Because it appears that the rest of the Washington press corps(e) allow administration officials to dictate and re-edit their quotes:

To our staff and to our readers:

As you are aware, reporters from The New York Times, Washington Post, Bloomberg and others are agreeing to give government sources the right to clear and alter quotes as a prerequisite to granting an interview.

To be clear, it is the bureau’s policy that we do not alter accurate quotes from any source. And to the fullest extent possible, we do not make deals that we will clear quotes as a condition of interviews.

With the government trying to do more of the public’s business in secret, the demands that interviews be conducted off the record is growing. While it puts us at a disadvantage, we should argue strenuously for on-the-record interviews with government officials.

When they absolutely refuse, we have only two options. First, halt the interview and attempt to find the information elsewhere. In those cases, our stories should say the official declined comment. Second, we can go ahead with the interview with the straightforward response that whatever ultimately is used will be published without change in tone, emphasis or exact language.

The fact that McClatchy is alone in taking such a position is troubling, to say the least..
