Relax, downstairs.
This is a free country with the Freedom of Speech Amendment in constitution. There is nothing wrong in this article for the reasonable doubt that Mao didn't "失节" unless you were the person who interrogated Mao at that time to certify he was not a fraud otherwise. I don't think to tell a lie to cover his 失节 to the communist party in that era in order to secure his position and reputation was a big deal for Mao.
