I don't think that it had anything to do with the problems with the Novus Ordo, at least not directly. He said he could not accept the Church's teaching on ɧoɱosɛҳųαƖity.
In other words, he'll be a Conciliar catholic again soon.
I am actually astounded at the speed at which ɧoɱosɛҳųαƖity has been completely and utterly accepted in Western society.
