Wow. This is a new one to me. I have not read or heard of anything like this but, if the person can prove it, I'd take alook to see what's up with it.
I grabbed that book earlier today and, never bothered to check the comments again til you mentioned it and, left the link. This is peeked my interest.
In the meantime, I'll search the net and, see what I can find but, if it's true....that would be shameful.
Let me know if you find anything out or if the person can back up the claim.
Stay safe.
