The reason is simple.
The ARC would ask him to prove that they are truly directed by holy spirit based on the failed policies to protect children from JW rapists. Then the general indifference shown the commission by the very ones that call and get the direction he is responsible for providing to the entire world wide church.
Especially the JC interrogations, shunning and two witness rule.
They might as well just have a JWBroadcast admitting that it was a for-profit, money-making scheme all along.
They'll just delete/DF the AUS elders that testified and pretend like nothing happened.
