SBF - "...It’s puzzling why Watchtower didn’t ultimately join the compensation scheme to avoid sanction and reputation damage..."
Pride is a significant factor...
...but more importantly, voluntarily joining would be tantamount to publicly admitting that critics' accusations were right all along, the problem existed in the first place, and that not only were the Org's vaunted "Biblical" policies unable to properly address the problem, but actually made it worse...
...all of which would too severely undermine the Org's claim of "God's Exclusive Earthly Organization" in the eyes of the rank-and-file.
And that is completely unacceptable.
Without that carrot/stick combo, there's virtually no incentive left to even be a JW.
Not to mention that at this point, they don't give a rat's ass about their public reputation...
...as far as they're concerned, they're in the Endgame Last Days now, anyway (on a fundamental level, they're all True Believers), so anything "Satan's World" does to them can't help but ensure/accelerate their salvation.
Seriously.
