Although it is a novelty to have so many photographs of Rebbes in the frum press, photos in private homes are nothing new. As a child in the 1950's and 60's I recall most Chabad homes had 'iconic' photos of their Rebbe, and Litvush Yidden often had personal photos of their Rosh Yeshiva or Rov. If more Haredim and Hasidim disregard their leaders' directves, it may be because there are so many more directives (interferences) than in earlier generations. I can't recall objections to concerts in my youth.
