I wouldn't be surprised if it's standard for them to ask everyone they engage to sign the NDA and they are told they can relay pretty much all of the meeting, barring maybe commercially sensitive info.You would expect that though, perfectly understandable.
But consulting a fan group that represents fans aboutn an interests, and asking them for an nda, is imo, a bit less expected.
Again, not that I am calling it secretive or saying anything negative about it as mentioned previously, there will be balance in it.
