Change is a constant in Cuba, as one might logically expect of a self-described "revolutionary" society. However, others portray this society as a monolithic state.
Does any of this matter to western audiences, with their short attention spans, and modernist tendencies to see the world through their own self-image? Outside commentators have been characterising Cuban socialism according to their cultural prejudices for half a century now, and no doubt will continue to do so. Those who look closer might understand a bit more.
