Well. They pretty obviously came up with Facebook but an idea and execution are two very different things. Zuckerberg made it was it is. If the brothers did it themselves we may not have fb today. It may have died. So they’re lucky a smart person “stole” it and made it into a multibillion dollar company and they got paid a shit ton for it. They were lucky imo. They claimed they lost out on billions. I say they got paid just for their idea and doing nothing else.
