I don't think your argument hold. I think this more about whether person has his/her own skin in the game. Lets take example, of a person working for company X and there is a claim Y which is related to company X. Lets imagine that the company is Google and the claim is "Google App Engine is one of the best cloud services". So when that person is on Hacker News, then he/she will agree with that statement. However, if that person start preparing a new company he/she will be neutral about statement "Google App Engine is one of the best cloud services" and will evaluate other services. Why? Because he/she has her own skin the game.
