I find it ironic the the Russian government placed the Watchtower's 'Revelation Climax' on the banned list because of its perceived extremism, but you won't find a Russian JW flouting that ruling by trying to distribute that book. Why? The governing body no longer believes the extremist contents of the book. Even now if JWs stubbornly hold to some of the teachings in that book they could be shunned or disfellowshipped and then labeled as apostates.
Think of all the JWs throughout the years that have risked their lives, or lost their lives, smuggling banned Watchtower magazines of which contents and teachings they have now thrown to the side as 'old truths' which actually means 'never Bible teachings'.
