What's right for consumers may not be, and often isn't, right for the business so it's not a case of "right" or "wrong" (because that can vary depending on who's point of view you're looking from) but a case of explaining why the strategy was taken.
>Denying every single "good" action in our professional lifes because it could cheat a shareholder somewhere ... that would definitively be a strawman.
No one said every single good action can be denied and, in fact, I explicitly said that I don't believe the people involved didn't have good intentions. However, if there was a choice to be made between increasing profits or "being good", a public company would often choose the profit route.
I understand what you mean regarding the accountability to the shareholders but I think it's used more as a euphemism to say that they are required to make a profit. They're more than welcome to have a philanthropic branch to their company but if you're investing millions of investor funds without financial gain, questions will be asked; that's the reality.
