I would write an entire book explaining all their false prophesies from the beginning as well as other issues such as child sexual abuse and distribute it to every Witness free of charge. In conclusion I would say that this organization is not worthy of existence and that all should leave it and let it collapse.
Then I would sell all their properties including Kingdom Halls and give the money back to the Witnesses in general and the victims of child sexual abuse which can be verified from their records as well as relatives of those who have died from lack of a blood transfusion.
Finally I would dissolve any legal entities that they have created.
