Anyone who questions the Governing Bodys authority is labelled as an apostate and almost always they bring up the story of Korah and his revolt against Moses.
Watchtower August 1st, 2002, the article Loyally Submit to Godly Authority paragraphs 8-15.

In not so subtle hint, the GB likens themselves to Moses, and those who disagree with the GB are Korah.
Paragraph 15 is actually quite damaging to the GB's argument though:
It was so unnecessary for all those people to lose their
lives. If only they had reasoned matters out.
But no one is allowed to "reason matters out" with Watchtower. Try, and find yourself in the back room with arrangements being made for a JC to shut you up.
They could have asked
themselves such questions as: ‘Who appeared before Pharaoh at the risk
of their lives? Who demanded that the Israelites be set free? Who alone
was invited to ascend Mount Horeb after Israel’s deliverance to speak
face-to-face with God’s angel?’ Surely the remarkable record of Moses
and Aaron gave proof of their loyalty to Jehovah and their love for the
people.
Yes, in the Australian Royal Commission, who was it that turned up to face their accusers? Was it the GB? Gerrit Losch denied even being a member of Watchtower. [http://jwsurvey.org/cedars-blog/i-do-not-answer-to-watchtower-stunning-gerrit-losch-declaration-revealed].
Jeffrey Jackson has to be dragged there, and even then only appeared by video link! They let their lawyers take the hit and even then they lied on the stand and twisted words.
Rutherford tried to curry favour with Adolf Hitler before WWII, and only when he was rebuked did he become anti Nazi. [https://www.jwfacts.com/watchtower/hitler-nazi.php].
Did a single member of the GB try to intervene in Malawi when the brothers and sisters were being butchered, raped, imprisoned and tortured?
No. Their own words condemn them. They dont do, and never have done, any of those things like Moses supposedly did.
No signs. No evidence. Nothing.
As such, any person is perfectly justified in asking for the GB's credentials. Korah, apparently, had seen the credentials of Moses but rebelled anyway. How are we in any way imitating Korah when we have zero evidence for the GB's authority?
