Because Oculus (now part of Facebook) was built on the NDA breach. (It is the court's opinion that) Luckey misappropriated trade secrets, formed that misappropriation into Oculus, and then sold that to FB. IANAL, but I suspect it's a 'receipt of stolen goods' argument - FB should have known through it's due diligence that what they were buying was stolen property.
