Ruckmanism spread rapidly among independent Baptists, causing them to have a major decline. God caused it to happen, by depriving their leaders of wisdom. Why?
Independent Baptists are not supposed to have any human leaders higher than a local pastor. But over time, various publications emerged, usually controlled by Godly men, and independent Baptist churches urged their members to subscribe. The editors of these publications gained power that the churches never meant them to have.
Decades later, these publications had turned Ruckmanite, and large churches and their pastors found themselves being attacked in these publications if they would not obey the editors. Pastors who wanted to depart from man-made rules found their people reading publications attacking anyone who departed from the rules. Conferences and radio broadcasts played a smaller part, and overall, independent Baptists were steadily being put under the authority of leaders whom they did not elect, who ruled through the authority of unscriptural offices.
These publications kept up active spy networks, accusing various preachers who associated with Christians who would not obey the editors. Pastors who wanted to learn and grow from unapproved Christians had to do so secretly, or avoid doing so altogether.
Sick of the fighting, many churches joined the Southern Baptist Convention, many individuals left for other churches, and many independent Baptist churches avoided the title "Baptist" in order to get away from these editors. Keeping the Word of God without the man-made rules, they are generally doing well, while Ruckmanites continue to separate into steadily smaller, hostile groups.
