DM: That’s a boldfaced lie that does not contain a single shred of truth in its deceitful untruthful attack against one of the Gedolei HaDor of the last generation.
Despite that, it is certainly true that Rav Elchonon Wasserman hy’d wrote (the ksav yad is available) that it is better to die a physical death at the hands of the Nazis than to be saved by YU which could cause one’s spiritual death.
