Ok, my 2 cents, I dont see why NVIDIA doesnt just settle with this guy for pennies on the dollar simply for good will. When I do business with people if they have any sort of basis (such as legitimately doing work for me) it's important to me to see them whole. I wouldn't be surprised if this person would have settled for even a 1% valuation ($10M is life altering money to >99% of americans) and it's not like they would have to pay it out, they'd just print the shares. (maybe vest it over 4 years too, har har).
Just my 2c and how I think about business. I get it's not the American Way™ but maybe it should be.
