I'm interested in the phenomenon by which the position "I don't think this is necessary for me" is expressed as "This is a useless piece of crap and anyone who uses it is a moron. Furthermore, the very existence of this item is evidence of a vast conspiracy by which untold forces to defraud the ignorant masses of their hard-earned money; a scheme by which I am infinitely too shrewd to be taken in."

Seriously, if you think the authenticator is stupid, can't you just keep thinking that without posting to tell everyone else how stupid they are for using one?
