It is indeed a kind of poisoned 'endorsement' that MetaMed could have done without, a Nessus' tunic. It's telling that he obviously didn't run it by MetaMed before publishing it, or didn't straight out decline to give a recommendation, instead of wrapping it in "I expect it will be corrupted like all the others". It's surprising after reading his recent elogy on Yvain, who's involved with MetaMed.
