Countries work differently than companies. In a country, you could assume that vast majority of citizens think of it as their home and wants to protect its long-term interests (however bad they may be at it).
In case of both VC-funded and publicly traded companies, investors/shareholders mostly don't give a damn about the company or the product, they just want to flip it for more than they put in. That promotes extremely short-term thinking and abusive business practices. A "dictator" who actually cares about the company and the product is better.
Which is Mark Zuckerberg? Probably a bit of both.
