What you say is true, but sometimes there is a power imbalance in which one party uses its power, connections and vendor award status to gather and selectively present information in a concerted campaign to destroy another. Being "neutral" in such a situation is to condone the result.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
