Politico quotes new policy in effect now at the New York Times:
“[S]tarting now, we want to draw a clear line on this. Citing Times policy, reporters should say no if a source demands, as a condition of an interview, that quotes be submitted afterward to the source or a press aide to review, approve or edit,” the new policy states.
The reason given by the NYT is unreasonable pressure on their correspondents to edit quotes after they were give and recorded. This, of course, is unacceptable, however I was under the impression that it was never allowed for sources to change what they actually said, only to check that quotes are accurate and not used out of context. That is, at least, our policy.
