They proposed they could be talking about teachers of religion that do not do their duty. They fail to call out the sins of the people. They fail to train the people up in the correct ways they should go. Many churches has paid clergy. That can make for a hard conflict since they work for the congregation and the congregation can fire them if they don't like the way they preach or what they preach.
I think Abinidi also taught some of this in Mosiah 12:25-29
