So instead of an unaccountable government agency, your only option for redress is an arbiter that the company you're complaining against hired. "Unaccountable" is another word for "provably uninfluenced". Arbitration is provably influenced.
(For your other points: "rich" trial lawyers that make, on average, less than software developers? "partisan" isn't the dirty word you think it is, ideas should be judged on merits regardless of source. Funding from the fed reserve is actually fairly brilliant, considering the continual issues with passing a budget in congress.)
Yes, that is the literal meaning of the word. However, when a government holds an agency "accountable", it is exerting influence over it. "Accountable" agencies have their effectiveness swing wildly depending on the current governing party's whims. "Unaccountable" agencies, like the Federal Reserve and the United States Supreme Court, carry on doing what they do regardless of whatever nonsense Congress is doing this week.
