I'm not sure you could ever say that a company can act ethically. People within the company may act ethically, but the company itself is just a legal entity that represents a group of people. The company has no consideration of ethics to act ethically.

A company that is composed of 100% ethical actors may one day have all their employees quit and replaced with 100% unethical actors. Yet the fundamental things that make the company that company would not have changed.
