Last I heard, Hershey was still using real chocolate in their two "showcase" items - the Hershey bar and the Reese cup - and switching to "chocolate-like substance" for their lesser items, like Mr. Goodbar, Krackel, etc.

But hey, if they want to shoot themselves in the foot by degrading their own product, I guess I can't stop them. But as others have pointed out, chocolate lovers know when they're not getting the real thing. You mess with us at your own peril.
