I would consider a good 'leak' to be something that can potentially be damaging to them. Just leaking information ahead of the official scheduled release date or 'elders only' leaks can help 'if' they expose them for something illegal, unethical, or not biblical. Otherwise it's just getting information ahead of time.
Now, if someone, can pull a Snowden on the WTS, I'll be the first to send them a fine bottle of whiskey.
