Indeed it would be huge news to anyone outside of the propaganda machine. It seems like they are trying to bring a change in through the back door. We've had news recently about how much work is being done at Chelmsford. Then this comes in through a letter to the BoE with no instruction to read to the congregation. Not only that but the letter does not reference any end of printing or anything like that, it simply talks about the fact that now Britain will do distribution. At some point it will all be obvious but since the change has been done with no fanfare it will be a seamless transition without the possible repercussions of a proper announcement.
Of course, all of this is slightly moot since an easy excuse is the move to more electronic distribution and the sheeples will lap it up anyway. But why make it a talking point at all if you can do it on the sly...
