Every successful organization has an administrative position to keep the organization centered and united.

Administrative position. In the formation, organization, and subsequent direction of the Christian congregation, the apostles occupied a primary position. (1Co 12:28; Eph 4:11) Although they were joined by others of the “older men” in such supervision, they formed a principal part of the governing body of the expanding Christian congregation, and this body was recognized by the early Christians everywhere as the channel of communication used by God to render decisions and direct the affairs of the congregation throughout the earth. (Ac 2:42; 8:14-17; 11:22; 15:1, 2, 6-31; 16:4, 5) This was possible for these men only because of the fulfillment of the promises about guidance by God’s holy spirit. (Joh 15:26, 27) Such help enabled them to recall Jesus’ instructions and teachings, to clarify points of doctrine, and to be progressively guided “into all the truth” revealed through them at that apostolic period. (Joh 14:26; 16:13-15; compare Joh 2:22; 12:16.) They made appointments to positions of service within the congregation and also designated areas in which certain ones would engage in missionary activity.—Ac 6:2, 3; Ga 2:8, 9.
je p. 26 Shepherding God’s Flock in Unity
The Governing Body consists of a group of anointed Christian men (13 in 1986), including 7 serving on the board of directors of the Watch Tower Society. These preside over the worldwide activities of Jehovah’s Witnesses. They are not inspired by God and hence are not infallible, but they rely on God’s infallible Word as the highest authority on earth, and have a lifetime of experience in submitting to God’s will. Each has a record of more than 40 years in the full-time ministry with Jehovah’s Witnesses.
There's no “blind allegiance,” as Jehovah's Witnesses and the Governing Body adhere to God's Word as the highest authority on earth, as was just explained. Some former members have an unhealthy obsession with their former brothers as explained in Mathew 24: 48, 49.
w94 7/1 p. 11 par. 10 At Which Table Are You Feeding?
Consider, for example, the food dispensed by the evil slave class and the apostates. It does not nourish or build up; it is not wholesome. It cannot be, for the apostates have stopped feeding at Jehovah’s table. As a result, whatever they had developed of the new personality is gone. What motivates them is, not holy spirit, but vitriolic bitterness. They are obsessed with only one aim—beating their former fellow slaves, as Jesus foretold.—Matthew 24:48, 49.
It's this obsession that populates the majority of this forum with activity.
