There is a reason that there are laws in place in corporate structure to prevent the activity that is happening here. Investing 10x what they have isn't a reasonable option because that is millions of dollars that pretty much no one has.
A director of a corporation can have 99% ownership of a company and bleed the company dry to fill their own bank account and what happens? Does someone need to buy their shares from them to make it right? No. They are removed from their position in the interest of the 1% of shareholders by a governing authority. We don't have such a governing authority, so this all comes with the territory, but it doesn't mean it's not going to do severe harm to the platform.
Calling them CEO's is not really accurate, because CEO's exist in a world where they are held accountable by a board of directors, by a governing authority, or the other share holders. Steemit whales are held accountable only to themselves and other whales.
