Some people are too diplomatically savvy to honestly and completely answer a question with very obvious answers about why certain people like Mark Z and Bill G are considered untrustworthy. They have to "play ball" and it's annoying watching someone have to tap dance around a question, just don't ask those kinds of questions if a person isn't the type to say anything negative about other people so they don't have to insult our intelligence trying to tap dance around the elephant in the room. We all already know the answer, no need to ask him.
