I think it’d be similar to Hirohito’s surrender to the Allies after Hiroshima and Nagasaki…
…he did it publicly over the radio, everyone across Japan heard it, and Emperor-worship essentially collapsed overnight.
Why?
Because a god can’t surrender. If he did, he wouldn’t be a god. He would, at the very least, be renouncing his godhood, or at worst, inferring that it was never real in the first place.
Either way, no more Emperor-worship.
Similarly with the WTS, it has spent a century insisting that it’s the only path to salvation. If it ceased to exist, not only would it be unable to dictate how loyal JWs live, but it would be the most elegant proof that it’s legitimacy was never real.
“God’s Exclusive Earthly Organization” cannot (be allowed to) collapse…
… if it did, it wouldn’t be “God’s Exclusive Earthly Organization”, which is its entire reason for existing.
