Facebook is "fighting false news" by forcing heavy moderation. But - they won't show group owners what content was against "the rules." If we approve something that is "against the rules" they will take down the entire group.

Let me be perfectly clear when I say that Facebook is a business, not a government entity. They have the right to censor or remove anything they want. Sure, it sucks but this is their playground and they make the rules. We all agreed to those rules when we made our accounts.
