"Third, corporate directors are not required to maximize shareholder value. As the U.S. Supreme Court recently stated, "modern corporate law does not require for-profit corporations to pursue profit at the expense of everything else, and many do not do so." ( BURWELL v. HOBBY LOBBY STORES, INC. ) In nearly all legal jurisdictions, disinterested and informed directors have the discretion to act in what they believe to be the interest of the business corporate entity, even if this differs from maximizing profits for present shareholders. Usually maximizing shareholder value is not a legal obligation, but the product of the pressure that activist shareholders, stock-based compensation schemes and financial markets impose on corporate directors.

A company's management has to act in the interest of shareholders, but that can be very loosely defined. A company that says "When making business decisions, we prefer protecting the environment over short-term profits, because our shareholders are humans living on Earth and without a good environment, our business would fail in the long-term" is not doing anything illegal. But if other companies don't follow suit, the eco-conscious company is in danger of being outcompeted.

S&P has a shariah index right across the border in Toronto Stock Exchanfe since forever while similar enterprisers push B-Corps and Public Benefit Corporations domestically as if they’ve “figured out” the code to sustainable for profit ventures through charter. Shariah in this context is very compatible with what these kind of investors and consumers are looking for, but they don't know it as they probably conflate it with human rights abuses.
People are just gullible, hope I unpacked that enough.
