A bit far on conjecture but does frame the narrative effectively....why did the Chief Pilot ignore the very standards and procedures he was supposed to be teaching others?
As to saying doing an IMC Climb to on top was his plan all along....I think that was a patently false statement not supported by the evidence.
The suggestion that the Pilot had to communicate with ATC ignores reality....that in an emergency, even one that is self inflicted, one may deviate from the Rules as needed to deal with the emergency.....and he need not have done anything but fly the aircraft to clear air that was above him.
The statement that it was only 30 feet to go before he would have broken out is a bit lame....as there is no way to know how close he came to breaking out before losing control of the aircraft.
