In a sort of self-referential loop, a large part of the propaganda value to many of these, certainly D.Z. in particular, is the fact that it was banned/censored in the USSR in the first place. Obviously that wasn't the only factor that gave it value. It had to have other elements to it (such as being written by one of the greatest Russian authors, provoking unconventional thought, etc. -- obviously banned garbage would have remained garbage). But a large part of its hit on the credibility of the leadership of the USSR, which is what gave it propaganda value, was essentially self-inflicted.
