I think you could argue that the Watchtower Society HAS died, jw.org is the tombstone on its grave. The religion I grew up in through the late sixties to the new millennium barely exists anymore.
90 hours for regular pioneers, 48 full issues of Watchtower & Awake! per year, PO's, CO's and DO's, midweek book study, in-person meetings only with Bibles in hand instead of iPads.
Door-to-door work instead of stationary passive carts. Magazine routes, S8's and RV's. Detailed (but admittedly insane) study material instead of the stultifying and infantilised cartoon propaganda spewed out now.
Honestly, if the shunning policy could be overturned so that young folks could leave without penalty or stigma I wouldn't care if their membership reached 20 million or more.
