I'm always divided on this as a shareholder, but more often than not I do trust the founders more than the open market, yes. They have an emotional stake in the company that goes beyond short-term economic interests, and I've seen enough companies flounder after the market jettisons the people who built it, and enough recoveries when the founders return, to question the wisdom of shareholder power.
Seriously. If the founders don't want shareholders mucking with their property, then don't go public. Stay private.
If you don't like founders keeping control, don't buy their shares.
There is nothing about going public that implies a general relinquishment of control of the company, nor is there anything about going public that mandates a particular ownership or power structure. Companies have "gone public" by selling only a few percent of their stock. Split voting rights are very common. None of this is even remotely illegal or unethical so long as it is disclosed, as it has been here.
If you do not like a company's control structure, you do not have to invest in it, whether the company is "public" or "private". As a shareholder, your relationship to the company is the same whether it's public or private.
