Shareholders own the company. Which is why people care what they think.
I have preferences for how my neighbors manage and maintain their properties, but since I don’t actually own those properties, my preferences don’t mean a lot.
As a customer of a company, I can decide whether I’m getting my money’s worth. As a general observer I might have an opinion about whether the company makes the world a better place. So shareholders shouldn’t be the only story. But I don’t think it’s strange to focus on what the shareholders think, or for the company’s owners to decide on corporate direction.
