For example, the US government collectively is not particularly famous for 100% morally upstanding behavior. Granted, the US behaves often better than other great powers, and certainly it represents many ideals of democracy and liberty more than other contending powers. But consider the mess that was Iran-Contra affair or the various regimes ranging from unsavory authoritarianism to sheer terrorism (with "disappearances" and torture) CIA supported in Latin America in the name of anti-communism. (God forbid someone propose an idea of land reform in South America or advancing workers' and natives' rights against UFC, despite that's how numerous European countries avoided communism.) Did these actions (and various other questionable shenanigans the US government has been partial to) represent your ethical positions?
It's everyone's job to do it, and what any government does is only part of that. For example, you mentioned AAPL stock owners. According to any sane ethical system, the moral duty of any individual CEO or a member of board or stock owner as a human person with rights and corresponding duties to act ethically overrides their financial or legal duty to maximize corporate profits.
