Sergey and Larry hold a controlling stake because there is a dual class of Common stock where the Founders' stock has 10x the voting power per share compared to normal Common stock.

If they put it to a shareholder vote and everyone decides leaving china is good that is fine. If they make a vote among a few insiders at the top and leave china and then it turns out billions in market cap are lost as a result, I'm almost certain there will be a lawsuit.
