One thing that can be said in honesty to fact is that all the leaders of the WTS were propagandists endeavored to draw attention to the literature the WTS published.
Pointing out the false worship of other Christian based faiths, promoting that mankind is living in the end time (This Generation) were all self supporting doctrines devised to support the proliferation of the literature the WTS published.
Of course these doctrines were not scripturaly supported if one were to carefully read bible but this was the cunning strategy the WTS took with purpose and self supporting reasons. People today still believe what the WTS leaders say in spite of condemnation written in the bible, specifically the words of Jesus Christ.
When one gets baptized as a JWS they are actually making themselves loyal and faithful sales representatives to the Watchtower Corporation (Publishing house) or now known as JWorg.
Preaching a tainted and false commercialized Gospel is what the JW religion is all about , many are starting to Awake and realize that.
