Just saw this : M/C Journal - How Free Became Open and Everything Else Under the Sun via Purse Lips, Square Jaw
But the M/C article misses a couple of points.
1) "Free software" from Stallman has always been a political idea. And one which can be understood as straight up "left" ie. a belief in communaly accessable resources rather than private property.
So it's slightly strange to say FOSS is broad enough to have been "adopted" by the left. It was theirs originally.
2) The confusion arises because of the move to the "right" - ie. from "free software" to "open source" - which was a deliberate political action by some people within the movement long before IBM et al became involved.
Look at the explicit writings of key people like Eric Raymond and Tim OReilly. Remember the terms "Cathedral" and "Bazaar" don't refer to FOSS vs. proprietory software. They refer to bottom-up, distributed vs. top-down, centralized ways of developing. Raymond is refering to market economies vs. centrally planned ones. In "Homesteading on the Noosphere" he is trying to assert the primacy of a notion of private property as the way to understand the political economy of FOSS.
3) Lessig doesn't strike me so much as a "Centrist" as someone moving to the left in this domain. Note he's now joined the Free Software Foundation, so is a member of the cathedral.
It's because they miss the *dynamic* history of this story, that the M/C seems to think that FOSS is just a broad idea suitably adaptable to different groups. In fact it's a left idea that's been "spun" for the right.
