OK, jimmothy:
You own stock in company A, which makes widgets.
I own company A, and want to make your shares worthless.
I form company B, and form a contract to sell it my widgets at laughably low prices.
This bleeds out company A, while I get to keep all muh munyz through company B profits.
So now you know

Well, What if "I", the owner of company A, himself possesses more than 50% shares of company A? And "I" take a risk by collude with all the board members, who possess another 30% shares, only to bleed the rest 20% of the company out...
The TL;DR answer is you don't own 50% of company A, or any company.
What you do own is a few ASICMINER sharez, worth ~50% less than they used to be just a couple of days ago. That's also bragworthy, in its own way.
Why start with outlandish hypotheticals when equally lulzy personal examples are at hand?
*Now that we're on the same page, what exactly did you wish to know?
Sorry, I'm not English native speaker, maybe I failed to express myself clear.
What I really want to mean is: FC himself already possesses more than 50% shares of AM through BitFountain. I don't find any good reason for him to take a risk by collude with all the board members, who possess another 30% shares, only to bleed the rest 20% of the AM out.
