Agree with everyone, especially if this article had shown up in Advanced Diver Magazine, NACD Journal, etc. But it didn't.

On the bright side (of the article, and not the death), this is an article that avers the dangers of cave diving + is aimed at the general public. Chances are that many OW divers (and yet-to-be-OW divers) may read it or have read it. Nothing wrong, IMO, with letting people know that it's dangerous in a cave, even if the message does smack of sensationalism.
