Executives know many things about their company that shareholders don't know. One of the responsibilities of senior management is communicating with various stakeholders and the efectiveness of that communication can have a tangible impact on the ultimate success of the company (irrespective of their product and services). I tend to agree that so far they have done a poor job of communicating in repsonse to questions but I fully expect there are material items that are not public (in fact I'd be worried if that were not true).
