Companies exist because society, represented by elected governments, considers them a useful concept. Their activity is assumed to be beneficial to society without any explicit requirements to that effect, because they operate in a free market where Adam Smith’s Invisible Hand generally applies.
It is strange how this is always being used to justify any and all morally reprehensible behavior by companies. If you expect people to, on occasion, go above and beyond the minimum required by law, there is no reason to hold companies to a lesser standard.
There are infinite examples where society noticed some less-than-ideal behavior in the pursuit of profits and acted on it, by, for example, legislating environmental, labor, or consumer safety standards.
At the other end of the spectrum, companies do regularly consider ethics in their decisions. This happens so often in fact, most any American CXO would be in jail if the crowd that keeps repeating that any consideration but shareholder value is prohibited by law were right. Google left China at some point for ethical reasons. Apple has invested earlier and more than competitors into environmental improvements. On labor issues, they have often done the right thing where a company like Nike, faced with very similar questions, has not.
Almost tautologically, any publicly known selfless act I could give as an example can be dismissed as still being done solely in the pursuit of money, by being PR exercises. But that just points at how easy it is to get around this fictional requirement to be amoral caricatures of capitalists: do as much good as you want, and call it PR!
Or, in Github’s case, point out how reliant you are on attracting talent. And ditch ICE in the name of recruitment, and, therefore, future profits.
