I actually think the expected reality is worse:

The family will likely settle out of court. MongoDB will admit to no wrongdoing and the settlement will be sealed and there will be an NDA signed by the family, essentially making it impossible for future employees to get the help they need.

If the family really, really cares about their daughter's legacy, they need to hold out until MongoDB is willing to admit to wrongdoing, even if it means they don't see a penny.
