As soon as digital technology perfected the separation of information as content from material form, the way was open for a massive socialization of cultural material. To some extent this took the vectoral class* by surprise. It did not quite occur to them that private property is not the "natural" form of culture.We are witnessesing a massive, nameless, faceless social movement, which takes the raw material of commodified culture and turns it back into common property. And the good news is that this movement has essentially won. After centuries of privatization, culture is ours again. This victory is partial and limited, of course, just as the victory of "socialism" in the West was limited. It only applies to culture, and not to many of the other aspects of vectoral power. But still, it is worth celebrating.
Politics now for the vectoralist class is the politics of attempting to recommodify some aspect of the value of culture, to make it scarce and rare again.
* What Wark calls those who control channels of information and intellectual property ('vectors'), e.g. Facebook, Apple.
If an autoreduction movement of millions communised billions of pounds worth of culture, would libertarian communists notice?

How often do you see communists talking about it? P2P is easily up there with the gains of the 20th century and while many of those are being rescinded, it continues to grow. When else in living memory has the working class imposed its desires on capital and won?
That said, Wark is right in that it's a partial victory both in terms of infrastructure to get on the internet for most of the world and the fact films, books, video games and music are still commodities. But as further generations see these things as a right, who is going to buy them? And if culture can be a right, who's to say it won't be food, transport or housing next?
