I would agree, but I don't understand why Facebook would file a lawsuit against Namecheap. I would have thought they'd file a lawsuit against John Does (the owners of the domains) and obtain an order from the Judge to compel Namecheap to reveal the names of the John Does.

Then again I haven't seen the court filings so maybe that's exactly what they did and Namecheap is just mentioned as an additional defendant.

Either way, I would also expect Namecheap not to reveal anything unless they are compelled to by court order or another legal obligation.
