Seems doubtful.
I think we on the forum and online generally don’t appreciate just how seldom “apostasy” crosses the minds of ordinary JWs. For most it’s just not an issue, until it is, then often they leave. You don’t get many JWs long term worrying about apostasy either in themselves or others. They’ve got other things to think about, such as all the talks and tasks they have to perform, the CO visit and so on.
