Earlier quoted context omitted.
The only point of a company is to maximize shareholder value. You're right, that doesn't always mean "maximize revenue at all costs.” It usually does though, because especially as a growth company that's what shareholders want. Obviously there are competing priorities, but overall most shareholders want to maximize discounted profit, and all their priorities reflect how that should be done.
That’s not true though. The shareholders are people so what they want are as varied as what people want. Does Elon want SpaceX to be super profitable or does he want to make life multi planetary? (They aren’t mutually exclusive, but it’s weird to think that he is just trying to make as much profit as possible).
People in control have much more ability to have the company execute their vision. As an investor the only thing you can do is say yes or no to management. Since the group of investors all have different side goals the one thing they agree on is making money, so management optimizes for that. Then everyone sees that the company exists to make money, so people that are interested in other things self select out. In the end all the shareholders are interested in maximizing the share price.
