Precisely. He/she didn't prove anything, instead falling back to the distinctly "original" not being able to answer any questions along that line. The fact that he/she could not provide anything to prove inside knowledge should be a ginormous red flag for anyone who employs a bit of critical thinking. There are many, many ways to prove you have inside knowledge of a situation without outing yourself. If someone is going to be an "anonymous source" the burden of proof is on that person to provide something verifiable. Anyone smart enough to be in a position to supposedly sign an NDA would be smart enough to establish validity. Would be willing to be that whomever that person was, cobbled together a bunch of other people's thoughts from here and other places, and passed them off as an authoritative first-person experience. The reason that the whole 404Architect shtick has caught fire is because it is feeding dissatisfied people exactly what they want to hear, to maintain that same mission of trying to belay the opinions of others - whom have equally valid, albeit contrary, opinions..
