It looks like they made a good attempt to answer your question. They are saying that the board's fiduciary duty is what lets them be trusted by the government to sell the company. They are not saying the board decides what a decentralized market would pay each individual shareholder (the stock market does that), but that the board has an obligation to evaluate an offer against the likely future value of the company if it proceeds on its current path. Reading between the lines, the market is essentially a) the current stock price, b) the offer price, c) what the board/SEC/shareholder lawsuit judge thinks is a reasonable difference between A and B.
