I don't think this is not so much a property of the big company than it is of the public company. The only thing which generally unites public investors is a desire to see a positive return on their investment, typically with a high aversion to risk.

I would argue there is something to be celebrated about the "richest man in the world". Large private investors are more accountable than the public, and can act on ideologies or intentions other than greed (for better or worse).
