I sort of think that libertarian Socialism, libertarian Communism, Autonomism, and, Communization all just simply refer to the political philosophy that is known as Anarchism. As Anarchism is the historical philosophy, it seems like people should just use the term, "Anarchism", to refer to said political philosophy. While I wouldn't go so far as to accuse Autonomists and Communization theorists of whitewashing Anarchist history, I do think that the usage of other terms does the school of thought a bit of a disservice. Anarchism can effectively be summarized as libertarian Socialism. I don't see a reason to use another term.
