You're right of course. However, interviewing is a game of limited information and I consider all signal I get from the company (after all, they're doing the same with me). I think a few things had to be broken in order for an employee to feel strongly this way, end up in the interviewing panel, and feel comfortable to share their views.

Nowadays it may be easier somewhat to get some insight into inner workings, but in 2006 there was no Blind, Glassdoor, etc. Sometimes the positive signals outweigh the negative. In my case they did not.
