Abandoned by their idol Robert Kurz:
Kurz, who achieved prominence as an advocate of overcoming an alleged "class struggle fetish" in the left, but who has apparently changed his mind since the AEG strike right in front of his Nuremberg doorstep, sounded on this morning like a champion of class autonomy, that is to say, quite reasonable. What is needed is an "autonomous, border-crossing movement" that must struggle for demands like higher wages and the abolition of Hartz IV, but which in light of the crisis can only do so if it doesn't give a shit about financial responsibility or the world market.

On the news that their demigod Kurz is now a "class struggle dinosaur", the PD collective committed collective ritual suicide.
collective suicide would imply that Principia has principles; I think it's more likely that they just went with it, and are now trying to out-Aufheben Aufheben.
