Hm...i tend to define dystopias as a subversion of the utopia concept.
Of course, this will almost always have political implications, even though they may in some cases be watered down to an extreme degree or be so allegorical that they can be interpretatively malleated into whatever political conclusions one desires to derive from them.
However, it would easily be imaginable that an author with a reactionary political point of view creates a dystopia that is not about a worst of all possible systems that terrorizes people for the sake of stability, but one where the desire for change and greater equality becomes the cause for the dystopian nature of the described system.
Even though i can't think of any examples for this, if i would come across such a work, i would almost certainly classify it as dystopian.
But to come back to the cyberpunk discussion, i don't think that cyberpunk is dead, it has just changed its focus to aspects that have always been part of the genre, but where not as much the focus of people's attention back in the 80s simply because they where much less virulent at that time compared to other aspects.
Transhumanist concepts have always been at the very core of cyberpunk -just consider Molly's cyberware, the cryogenics and cloning habits of the Tessier-Ashpool clan, the rewriting of Armitage's memory or Wintermute in Neuromancer.
From the viewpoint of poststructuralist body studies, that book is pure gold, Lacanian readings being much more rewarding than those reigning from Marxist literary criticism.
It is no surprise that they have gained such a salience in contemporary iterations of the genre and that tropes now appearing outdated, such as the evil zaibatsu, have decreased in importance.
Such attempts also don't necessarily have to be apolitical, the current setting of SR, for example, offers so many possibilities to discuss topics such as freedom of information, the capitalist flipside to transhumanism, the possibility of liberated enclaves in an otherwise oppressive political structure, the relationship between state and economy, civil rights issues and so on.
Of course, these are merely hinted at in current publications, but if you want SR4 to be a game where the depraved and dispossesed stick it to the man, it is easily possible.
There is no, and there has never been any, need to play SR mirrorshades black ops style (although this can easily be achieved by playing down certain aspects of the setting, which is much easier than introducing aspects of your own).
If anything, pink mohawks are coming back with a vengeance.
We have so many options available to players in this edition that only or mostly make sense in a pink mohawk campaign, so many settings that practically scream for such a kind of game, be it Hamburg, LA or most likely all the locations to be detailed in Feral Cities.
