Touch out of date I'm afraid. The NYT has changed it's story:

"The kidnappers had demanded silence. “Possibly by defying them, we would be signing David’s death warrant,” said Bill Keller, the paper’s executive editor."

So far nothing suggests that wikipedia was told anything other than the original version of the story.

Yes, the story has definitely been evolving over the past few days. However, I've tried to go lighly on the specific reasons, and focus on the relative success of the media blackout and the processes involved. That's of more general applicability, I hope, even if specific facts change about this particular case.
