I guess I have a different take, and I've said this many times before in prior elections. Yes the moderator was unfair in questions and time spent. But that should be a real leader's time to shine, to show how they can overcome even that.
The job they are applying for isn't a cake walk. They are going to face tougher questions and bigger challenges than some moderator who asks them more follow up questions.
Bias exists, you aren't going to eliminate it. What you can do is use it to your advantage to shine that much more, not use it as a crutch to make excuses.
