This is a really bad idea. The best way to work against the machinations of the Watchtower is to always have agents of truth within.
The sad truth is no matter what tactic we use, the Watchtower will probably never change. Change will never come from within. Raymond Franz tried that. It didn't work. If you had 4 or 5 Raymond Franz's reach GB Pope level, then you'd have the possibility of change, but that's a crap shoot. Our main effort here should be raising public awareness so that the public sees the JW religion for what it truly is. If the organization changed a few destructive policies, I'd be fine with them believing what they want about God, 1914, this generation, etc. It's their right to believe what they want in this regard. However, it isn't their right to divide families because someone decides they no longer believe those very things. It isn't right to cut people off from their closest friends.
If these harmful policies receive enough negative publicity, maybe they will change, but probably not. The best we can hope for is that the general public will become aware of these policies before it is to late and they find themselves in the same position that many of us were/are in.
