Did Archbishop Marini lie?

Former Papal MC, Archbishop Piero Marini has written a book, Io sono un Papa amabile. Giovanni Paolo II, in which he states that Blessed John Paul fully approved of the offbeat liturgies that Marini was in charge of. Father Z. and his most of readers are dismissive.  Is Fr. Z saying in a round about way that an archbishop is lying to sell books? I know many people can't stand Marini but let's get real. Do you really believe that the pope put up with Masses he couldn't stand for two decades? That's absurd.
