It's all a word game. Historically, the Faithful and Discreet Slave is a composite group of anointed ones. Individually they are "domestics", as a whole they make up a class, and as a class they "feed" each other in the household. They have a representative, in the form of the Governing Body, which takes the lead in providing the "food" for the household.
Of course, in practice, this has never really operated this way. The top of of the organization (be it the office of the president or GB) determines policy and doctrine.
However, there is a subtle shift taking place. A shift that diminishes the position of all those that claim to be anointed and further elevates members of the Governing Body. Some of this they have brought upon themselves. The 1935 claim that the Great Crowd ingathering started and the ranks of the 144,000 were filled, could no longer be sustained with the passing of time. This had unintended consequences, with the memorial partakers increasing, probably to over 10,000 this year.
Now, they have been forced to act (in print at least) in order to reinforce and maintain the perception of concentrated authority in the hands of 9 men. I have never seen articles before that move to solidify the Governing Body as the actual "Slave" of their Matthew interpretation; it appears to be a growing underlying theme with the introduction of the Study Edition Watchtowers. This may be a significant move to the far-right. They are decaying from within with massive turn-over, they have a brain-drain, 2014 is closing, and the evil internet is exposing their true history. Some of the old guys may have backed off after the early 1980's and had some conscience about promoting their role after the 1975 and RV Franz debacles. But now (except for two) the GB is all new, have no direct knowledge of the issues of the 1970's, have no link to the 1914 era, and they think they are on a mission from God.
Ignorance and hubris is a dangerous combination.
