GB 1.0 had followed the eras of Russell, Rutherford, and Knorr. To be such a visible leader was to also have a giant target on you. Those GB weren't at all shy and retiring, but I think they realized that they didn't want the level of attention and scrutiny that would come with being "JW rock stars" like those previous presidents.
I don't think the current GB 2.0 realize this. The closest they've come has been with Jackson hauled before the ARC. This is their new reality. Now that they have plastered their names, faces, and voices on the Internet, advertised their current and future addresses, and done the same with their GB hamburger helpers, they have sealed their fate according to their own prophecies. If they really expect government to attack religion, the GB can expect to be the first ones trucked off to the concentration camps when their new headquarters will be turned into President Trump's rural retreat! LOL.
