That’s not a requirement of publicly traded companies. Any corporation has the same obligation to put shareholder interests first, whether it’s closely held (like Valve) or publicly traded but still under the founder’s control (like Facebook) or publicly traded with no one owner that exercises significant control (like IBM). The court case that established that corporations have a duty to shareholders above everyone else (Dodge v. Ford Motor Company) involved a closely held corporation (not public) and also confirmed that the corporation’s management can exercise its own judgment and discretion in prioritizing long term over short term gains, or vice versa.
