It's probably true Zuckerberg broke some contracts and maybe stole some IP, but the Winklevi seem to think that if Mark Zuckerberg never existed they would have been able to build Facebook into the company it currently is therefore they're entitled to X% of Facebook's current value, which is completely ridiculous.
So far the only thing proved is they had an idea similar to Facebook (as did probably dozens or hundreds of other people at the time) and they're [kind of] good at filing lawsuits. If they want to be known for anything except "those guys who almost-but-not-really created Facebook" they should move on and build their own great company with their $100M+ from the settlement.
You're probably right about that but the fact remains: Zuckerberg did them wrong, we don't know what would have happenend and someone in a similar position made billions with their idea and strategy. How they hypthetically would have executed if they had hired someone trusthworthy should hardly matter in a court.

But they won't, because they know they can't.
