You would think at this point in time - after thousands of bethelites were sent home; many thousands of rank & file JWs are at or near retirement age with No preparation - that the religion would change its tune - you're right, any reasonable person would think that the religion would change its tune.
They are still stubbornly sticking to their guns on this issue - we're dealing with a religion that thinks all its members - including children - should refuse blood transfusions in life-threatening situations. Remember, too, that this religion's official policy is not to report (or encourage parents to report) allegations of child abuse unless the state explicitly requires it.
JWs aren't reasonable people, that much is clear.
Hopefully WT stubbornness will backfire on the organisation.
