Good analysis.
Actually, there are many "study" articles that are completely recycled. Sometimes virtually word-for-word copied and pasted.
Let's face it, there's only so many ways to present the primary, fundamental doctrines of JWs:
-- The GB are godlike and to be obeyed unquestioningly
-- You miserable rank & file JWs aren't doing enough
-- You miserable rank & file JWs aren't behaving well
-- We need your money
-- Bad guys are gonna get ya "very soon now", so shape up
-- You should treat anyone who disagrees with us as lower than the parasites who feed on pond scum
How many ways can you dress up those teachings? It's inevitable that things will be repeated.
