If you read his essay, he states that this wasn't an "interview", the reporter was doing background for another story on Jessica. It was never intended to be an interview.
Publishing remarks made as part of background for a completely different topic, in such a way as to make it seem as though they were made during an actual interview on the topic quoted, is unethical, IMO. And since that's what happened, I stand by my remark.
So, you're just wrong about this. Filed under: Ethics - Human Sources: "'On background' is a kind of limited license to print what the source gives you without using the source's name."

And, knowing many journalists, none of them would ever print something given to them on background with the source's name attached. It is unethical.
