Yes of course JWs are tried and tested, repeat offending false prophets!
If it all went pear-shaped for the JW org (and the sooner the better!) for those who have had the Watchtower 'lobotomy' performed on them, the demise of the organisation will not alter their belief system so much.
Even without a large network of meeting places and spiritual enforcers in the form of circuit overseers, the cult mentality will remain internalized and they will no doubt pay the JWTV company to console themselves that thereby they are doing good deeds in life.
It is conceivable that the end of the JW organisation will be a late night televangelist spot whose audience will be a declining number of aged desperadoes once infected with the Watchtower delusion.
