A letter accompanying the 2010 revised, softcover textbook entitled "Shepherd the Flock of God" - l Peter 5:2 states:
"We will leave it to each elder to decide what he will do with his 1991 Kingdom Ministry School textbook. If he decides to keep the book, he must make sure it is put in a secure place so that others do not have access to it. Otherwise, the book should be completely destroyed.
We would like to emphasize the importance of keeping these new textbooks secured and confidential, both before and after they are distributed. The textbooks should not be left on tops
of desks or in other places where they are easily accessible by family members or other individuals. The information is designed for use by the elders only, and other individuals should not have any opportunity to read the information."
There are no conspiracies.
Anyway, this has probably been posted already, but surely worth another go.
