No, there's a concept of "burden of proof" which applies here.
You don't get to stack "hand waving" indefinitely. The person who made the original claim is responsible for providing refutable evidence.
I was reading through the comments and hoping someone would know what keystone actually was and if there was any possibility of the claim in the article :) . I mean there's a lot of stuff in chrome other than this keystone thing, maybe it was one of those other things.
