That's easy to answer, the reason this phenomenon happens is that most people are fucking unintelligent and tend to criticize things they don't understand. Which of course draws the crowd of even more stupid people who don't even have a real opinion. So in order to compensate they tend to gravitate towards negative the criticisms because it makes them feel relevant. Its especially ironic that in this particular game, one of the pervading themes is cognitive dissonance.
