The Watchtower has always made it a point that Jehovah has used "organization" to bring his message to the people. What it has failed to recognize is that God more often than not had to send individuals to warn the organization of its serious failings. Jeremiah is a good example. The temple organization was corrupt because of the sins of its leaders and the abuse of their powers. Not only was it prophesying falsely but it was exploiting and robbing the public. Jeremiah's strong condemnation of this system became a by word in the English language: "jeremiad: an elaborate and prolonged lamentation or tale of woe."
In the same way, Jesus and the apostles were the Jeremiahs of their day. They strongly condemned the religious temple system and its leaders for abandoning the worship of God for their own self aggrandizement while still trying to project a holy appearance. The Watchtower leaders would do well to learn from these examples.
