All of their rounds have added up to $333M; most of that is in the past 3-5 years; the early investment rounds were very tiny. $500M on $333M isn't the home run that the investors were looking for, but maybe in today's environment may be the best they can hope for. That said, they may not want to set that precedent.
They wouldn't necessarily have to give up any ownership, so they could keep hoping for a home run to occur later. I feel like that's a pretty good deal.
