I think this could be true. In some ways it’s the natural extension of halting literature production. Why do you need to measure “publishing” activity when there’s no literature for people to distribute?
It would have massive implications for how the organisation functions. For example will there still be pioneers? How will they define a pioneer, if not hours? I guess the concept will need to be redefined or dropped altogether, and with it much of the incentive structure that currently keeps the organisation functioning. Other churches function without counting hours, but they have other incentive systems in place which JWs lack (for example congregational autonomy, which is a powerful motivation for congregations of other religious groups, is completely lacking with JWs).
It really does feel like the GB believe the game is up, so they are drawing down their assets, and winding down the organisation.
