I think Ray Franz exposed a truth that is probably still true of today's Governing Body. I believe even their brains and thoughts were hijacked by the organization and working your way up to the Governing body might allow you to wake up some, but most just learned to cooperate because they feel like they finally got the brass ring. The individual GB members probably think that the other members are hardcore believers but that "I see that the emperor is naked." They probably do, to some degree, laugh at the rank-and-file in their Wednesday morning secret meetings.
They are duped themselves, no matter how much they realize its all a scam, into believing it is of the utmost importance to protect the organization ahead of any individuals. Changing doctrines becomes a game of making it all work somehow yet changing it radically to fit the calendar or money situation.
They say all the different things to cover whichever way they later might need to go. Jesus' 1000-year reign started, did not start. The anointed will still be here, they will all be in heaven already. God's loving kindness is a free gift, you must earn undeserved kindness. YADDA YADDA YADDA!
