Because the author of this article, Jeanne Lenzer, works for the British Medical Journal and WorldNet Daily didn't bother to credit her.
So it's a poorly produced online site; so what? The article served as a port to the *original source material.* That's what people should read and evaluate if interested. Sometimes a poorly written, poorly produced broadside is the first outlet to bring people's attention to something.
And remind me again -- that discredits the actual material exactly how? I mean, you are arguing against the original source material, so I presume there must be a reason.
For your convenience, the original source material:
