I agree that the GB has been grooming the flock to accept changes without questioning the leadership.
a) Those changes may seen illogical from a human point of view (read: they are huge doctrinal / organizational changes, that challenge the flock's perception that this is Jehovah's organization.)
b) The Organization is, for all ends, equal to Jehovah. If you're ready to obey God without hesitation or questioning, do the same towards his Organization, because they are "one", just as Christ and the Father are "one".
c) Recent "new light" on the meaning of "Generation" (overlapping generations of anointed christians); faithful and discreet slave (not anymore the anointed class, now it's solely the Governing Body, appointed by Christ in 1919); the exclusion of Russell from any connection with the appointment of the slave (by moving the appointment of the 'slave' to a date after the death of Russell, they managed to exclude Russell and his teachings without having to renegate him - so he can still be honored and venerated, but his fundamental teachings can now be abandoned because he was never part of the 'slave'.); The new understanding of the "3rd heaven" (the GB now concedes that there is a paradise in the spiritual domain, after all).
d) The re-branding of the Watchtower into "JW.ORG"
e) The promotion of the jw.org website as the ultimate means of teaching people world-wide, and drastic slow down in the printing of literature; downsizing of branch offices and printing facilities and staff.
f) Erasure of staff on the payroll: Bethelites and District Overseers. Vast empowerment of Circuit Overseers, while at the same time reducing liability exposure from Bethel.
g) Emphasis on "new" methods of evangelizing (literature carts, street stores, trucks, book fairs, website, e-publications), and less investment on door-to-door evangelizing.
All these recent changes are a strong 'composite sign' (see what I did there? ) that major changes are coming. They won't be pretty for the old-timers and the die-hards.
