Imagine you're Mark-- totally sick of running your company, dudes are getting in your way while you're carrying your scrumptious coffee-beverage to work (idiots), and no one really understands your pure awesomeness... you have maybe 10,000 BTC (idk!?!?) and someone offers you millions!! to walk away from gox == yummy coffee-beverages without idiots.
What would you do?
Win-Win-Win

That'd be visible in the source code repostory history,... wait. Maybe he doesn't have that... anything is possible.
