A person in the FCC with past in the industry can be biased in favor of their previous employers
in some ways, and not so biased in others.
In other words: the bias can be unintentional or subconcious and systemic ---- For example,
it can lead to certain ways of thinking about certain policies ; However, in extreme situations,
they will not overtly side with their past employer when it would be obviously to
unfair degree against the interests of whom you are supposed to serve.
A good outcome out of a few policy definitions cannot definitely affect this for the positive.
It can be very easy to prove bias exists, if you have an extreme enough pattern.
Proving no bias or "fair treatment" not counting more than fair weight to the corporate position of
previous employers, in policymaking consideration; would be extremely difficulty (if impossible) to ever establish.
