Corporations have PR departments too, of course. So investors should be skeptical. Put another way, what management wants is friendly. What it objects to is unfriendly. Shareholders must evaluate management before investing and determine if they can place trust in it.
Investors do have some legal protections against management and board misbehavior.
State corporate laws invariably require that boards of directors owe a legal duty to shareholders to act in their interest. Corporate counsel and threat of litigation generally ensure that management flies right. A court ordered the return of half the shares. Of course, a board member who is a substantial shareholder can enforce shareholder interests. It's to remind investors to evaluate management and keep track.
