"they have admitted they are not inspired"
The Governing Body is inspired the same as Paul was inspired. The thing is, people don't understand what the word 'inspired' means. While it can mean getting direct messages from God, mentally, audibly or in vision, the word inspired means where the idea came from.
Movies are inspired by true stories. Songs are inspired by events in the writer's life. So when Paul writes that all scripture is inspired of God, he means Gen - Malachi originated from God and the focus and idea of the apostles' writing was from those scriptures and for the serving God.
That's how the Governing body is inspired by God in that they use the scriptures as a basis for their serving God, not that they got direct information from God, Jesus or the angels.
