I think they closed rank on who the FDS was because the "remnant" scattered around the world were seen by the GB as getting entirely too full of themselves.
Little peon "anointed" in their own Halls and along the side ways and by ways were uttering their thoughts and regular publisher people were "ohhh" "ahhh" over it.
The change of the overlapping generation was an ideal time to just change the base of power also. Pull it back in to a straight up and down arena of control of 7 men in NYC.
Naturally, this has resulted in more disgruntled "anointed" ones round the world. Some of started websites critical of the GB in NYC but for the most part it is unimportant to the publishers it would seem.
