Really? I mean really? Of course it changes the value of the article- articles written by unreliable sources are less valuable than those written by reliable ones. Or does it not matter as long as you like the message? If the CIA/NSA comes out and says "Oh it's ok y'all should totally get stoned" does that mean you trust them all of a sudden?
It's no wonder every decent novel about a dystopean society has some type or psychoactive available-everybody trusts their dealer I guess.
