From what a Bethelite had said, Anthony Morris III resigned because he did not agree with the changes that the governing body was approving.
A user had written that the material for the annual meeting is prepared in February-March but is approved before. Maybe I sound crazy but things coincide, the governing body brings in two new members to have an overwhelming majority on the changes to be made such as hours in the service, beards, last minute repentance and the new ones that will happen soon that will have a notable impact, Morris votes against and creates problems for the body by blocking the changes, but he is in the minority and they put him on the ropes, in the end he leaves and slams the door.
I find it strange that AM3 still hasn't contacted or spoken to any of his friends who think like him and this information still hasn't reached the internet. But the latest leaks seem to give the impression that AM3 "is singing"
