This is an older text, from 2005, but it's still one of the best on the issue of the paradoxical relationship between the attempts to privatize knowledge and its inherent tendency to be social, because it's based on a shared language.

Theire wisdom’s so profound, to cheat us of our ground
Stand up now, Diggers all.
The Diggers’ Song, Gerrard Winstanley & Leon Rosselson
