Yeah, that's not how equity investing works. Even if you assume he had the worst in terms of anti-dilution provisions, that's still gonna be like 5% of a $50B company. If he gets Zuck's anti-dilution provisions, that's more like 20-25% of a $50B company.
I think what I said came out bad, what I mean is if the question of ownership was at a certain value, as in the value at the alleged time of sale can you really lay a challenge on it at any future point in the company for say that 5% diluted equity. Seems to leave the door open for people to create technicalities in deals and then treat it as a risk free investment, if they can challenge for it back at any time into the future.
Why wouldn't you be able to? Zuckerberg didn't allegedly defraud the plaintiff of cash, he allegedly defrauded the plaintiff of pre-Round-A Facebook shares. If I steal a lottery ticket from you and that ticket subsequently wins the Mega Millions or whatever, I don't just owe you the $5 ticket price, I owe you the lottery winnings, right?
