Time for a recap and a look at the big picture. Assuming the above is true...
B&H, one of Nikon's largest retailers, openly sells grey market lenses. Nikon apparently has no problem with that or they would stop it.
B&H, and others, have sold tens of thousands of lenses to people over the years at a time when apparently Authorized Repair facilities were servicing those lenses. At least according to numerous posts here over the years, where it is usually suggested that grey market can be serviced by "anyone but Nikon".
Now, those buyers - new buyers as well as old that apparently are not "grandfathered" - are absolutely out of luck unless they can find someone to "steal" parts for them on the "black market".
