The directors and officers of a corporation owe a fiduciary duty to shareholders, not to customers. If the directors or officers do something unreasonable and tank the corporation's value, the shareholders or ownership can sue the directors or officers for the breach of duty. That could include revealing information that would benefit customers to the company's detriment.

They might also screw their workers by closing the doors without notice and then not issuing final paychecks or honoring other compensation obligations.
