Sirona,
IpSec is in a catch-22. He finds himself in a cult with a responsible position. He needs to do a few things. He needs to help others learn of the cult. He needs to keep his good relationship with his family, if possible. He needs to quit the cult.
If, in order to accomplish these things, he needs to tow the Society line and put his thoughts in the background so be it. He is trying to take the middle road of a lose-lose situation. He can't win, not in the short run. It takes time to set the stage and make your way through the landmines exiting this cult puts in front of you.
He is only telling the congregation members what it is they want to hear. He is telling them what the Society has printed for him to tell them, which is exactly what they want and expect. He is not lying or misleading them. If he tried to subtly add apostate teachings to his parts or discussions then he would be lying and misleading them. Even if it would be for their benefit it wouldn't be right.
Based on what IPSec said about attending the bookstudy with the Daniel book being studied I would say he is having a tough time and instead of berating him for his course we should be encouraging him to stay true to himself and his family.
Just my opinion, of course I just stepped aside as an elder myself so your post hit close to home.
