They only confirmed publicly stated info by BA, nothing secret that is in the NDA. I know your heart is in the right place. Call the China offices and report back with your results. Otherwise, you are just being a fudster.
Exactly. NDA does not mean 'no one can talk about anything', necessarily. An NDA specifies what cannot be talked about but it's not the same (again, not necessarily) as not being able to talk at all about a matter. Depends on the specific NDA, and I guarantee you that ba's NDA with their resellers isn't the same NDA as they have with veriwhateveritscalled. So claiming anyone has breached an NDA Is reaching a bit unless you've read that specific NDA for yourself.
(And yes, I've read, and signed, a few NDA's in my time, and they all had different things I couldn't talk about in them)
