One of the really interesting things that you say about preference falsification is that there are ways to express your discontent with the regime or with te new system. You have to do it in a way that is subtleand one of the ways you can do it is through humor. Humor is used in repressive societies and in contexts where people feel constrained in what they can say, without taking ownership of the preferences being expressed or the facts being pointed to. In laughing, they signal that they understand what is being communicated but don't have to take ownership for it.
