postmodernity - controversial?

Postmodernism could be seen as controversial theory because it is stating we lost belief in progress and that media's becoming meaningless heading towards a dystopian future, which may not reflect positively on the culture as we are creating more and more of empty, devalued products. The theory in fact became a tool to control the society. No meaning leads to no personal opinions, therefore everyone thinks the same so it's easier to control the society.
