For those that are convinced they are not following man, but Jehovah, this example is 100% proof they follow men. If they twist this to say they don't follow man, well, there is no hope for them.
The Bible is very clear to honor your father and mother, it was and is so important, it's listed as one of the 10 Commandments. When that parent leaves the truth, either due to disassociation or being disfellowshipped, the child shuns them for life. How is giving your father or mother the silent treatment for the rest of their life showing them honor? It's impossible, and if some JW can reason they are, there isn't any hope for them. As I said, the Bible is very clear that Jehovah wants you to honor your parents. So who will you listen to, Jehovah and his Word, or man?
I recall a monthly broadcast not too long ago by Brother Lett. I think he was saying we need to be totally obedient to the Slave, then he added, unless it was in violation of the Scriptures. I can't think of a better example where we would not be obedient to the Slave.
