"It’s been rumored that Facebook has lied about how many people actually use their service. However, if it’s good for investors as well as stockholders, does anybody care?"

It would only be good for those stockholders who happen to sell their stock before the truth becomes public. The rest would suffer as the market re-values the stock downward based on the real usage numbers. (And since Facebook is a publicly held company, a material misrepresentation of the company's condition could incur the wrath of the SEC.)
