Could you add a clause in any (subsequent) contracts dealing with this possibility? If this contract is valid, Zuckerberg would have known about it ever since

Could you add a clause in any (subsequent) contracts dealing with this possibility? If this contract is valid, Zuckerberg would have known about it ever since 2003. If his business associates knew about it, would they have dealt with the situation proactively? If he chose not to disclose the information, maybe he'll be seen as a danger to the future prosperity of the company?
