A "Fiduciary responsibility to shareholders" means exactly what I said: "legally bound to extract profit without these silly notions of empathy or trust".

The only notions of empathy or trust you see from publicly traded companies nowadays is the over-engineered calamity of ESG. If you have a single example of a moderately-adopted trend which demonstrates a genuine desire to do right by their society, or to build long-term trust at the expense of short-term profits, I'll readily adopt it into my world model.
