Primitivism could be defined as anything pre hunter-gatherer tribalism, anarchoprimitivism seeks to deindustrialize and and destroy technology, some even call for the abolition of language (as if that were possible), and then there is primitive communism which is when there was no no private property because society was not so advanced to have any meaningful kind of hierarchy.
In my opinion, anarchoprimitivism is the equivalent to zombie apocalypse aficionados, who unconsciously wish so much for capitalism to end, therefore any possible outcome is better than current material conditions.
