I think this was an temp to pull a bulgaria on everyone in the world.
By saying that fractions are a grey area they were hoping that the brain washing would kick in and cause the R&F to say in they're heads "hey this is a grey area what did the FDS say about grey areas oh stay away from them".
( Your old fence setter analogy. Fence stters I.E. neutral people and thing are really evil people and things, they thought the black and white black thinking would take care of the blood dilema.)
Hence the GB would be able to say it is up to the R&F to decide what they want but they thought that the R&F would do what they told them to do in the past.
I think they forgot about the 1975-1980 drain and refill. The new R&F did not have the programing hence when they heard it's up to you they decide hey I don't want to die so I will take these fractions it only gray.
To make it short the GB blood plan backfired in they're face.
Anyone else agree.
