Doesn't this entire discussion demonstrate it ain't so? If the company has a revenue of $1B and pays the CEO $1B then it has zero profit. So how does the contractual obligation work out here? If you don't get a say on whether the CEO gets $1B in salary then what exactly is going on here?

There are other situations like the company taking on debt, issuing more shares, bankruptcy, acquiring other companies, share buybacks, dividends. If you don't have control there are ways for the company to "steal" your share of the profits.
