Much like the Wizard of Oz.
The people kept as mushrooms, the obedient members who obey the command to "not listen to the voice of strangers" know jack squat, to them WT is still the keeper of divine secrets and the arbiter of who needs to know For anyone else much of their so-called "secrets" are available online.
I still reckon they have secrets though, and not the organizational smoke and mirrors 'look we can pull a holy spirit rabbit out of our asses" kind either. They are doing something dodgy I can feel it in my buns.
