Here is a site that discusses the history of TWBTS how and who and what it was. https://en.wikipedia.org/wiki/History_of_Jehovah%27s_Witnesses
In 1881, Zion's Watch Tower Tract Society was formed as an unincorporated administrative agency for the purpose of disseminating tracts, papers, doctrinal treatises and Bibles, with "Pastor" Russell, as he was by then called, as secretary and W.H. Conley as president.[28] Three years later, on December 15, 1884, Russell became the president of the society when it was legally incorporated in Pennsylvania.[29] He said the corporation was "not a 'religious society' in the ordinary meaning of this term,"[30] explaining: "This is a business association merely ... a business convenience in disseminating the truth."
Russell warned: "Beware of organization. It is wholly unnecessary. The Bible rules will be the only rules you will need. Do not seek to bind others' consciences, and do not permit others to bind yours."[36]
Elders and deacons were elected by congregations and Russell tolerated a great latitude of belief among members. He discouraged formal disciplinary procedures by congregation elders, claiming this was beyond their authority,[37] instead recommending that an individual who continued in a wrong course be judged by the entire ecclesia, or congregation, which could ultimately "withdraw from him its fellowship".[38] Disfellowshipping did not mean the wrongdoer was shunned in all social circumstances or by all Bible Students.
In 1931, the name Jehovah's witnesses was adopted,[4] further cutting ties with Russell's earlier followers.[5] Substantial organizational changes continued as congregations and teaching programs worldwide came under centralized control. Further refinements of its doctrines led to the prohibition of blood transfusions by members, abandonment of the cross in worship, rejection of Christmas and birthday celebrations and the view of the biblical Armageddon as a global war by God that will destroy the wicked and restore peace on earth.[6] In 1945 the Watch Tower Society, which Russell had founded as a publishing house, amended its charter to state that its purposes included preaching about God's Kingdom, acting as a servant and governing agency of Jehovah's Witnesses and sending out missionaries and teachers for the public worship of God and Jesus Christ.
It is the Society that makes up the rules and the JW's who follow them without question. You can definitely feel the WT corporate authority, the obsession with obedience and the desire that all JW's march in rank no independent thinking is tolerated.
The fear of shunning and loss of family members is the way they keep their members in check. They will say that it is the way they can keep the organization clean and protect their name.
Unfortunately the recent revelations about chronic pedophile problems is casting a long shadow on just how clean this organization and this religion is.
