I read this because the reference to "the trap of amateurization" in Piracy is the Future of Culture had caught my eye and I wanted to hear more about this. Unfortunately there's not much beyond what one might have inferred without reading the transcript or listening to the exchange. There's a good point at the beginning about the relative simplicity of tech work versus "simple" social interaction, and how this perception is a piece of a patriarchal perspective that favors traditionally masculine work and shortchanges traditionally feminine work. Otherwise, this exchange takes place in July of 2006 and is pretty steeped in the techno-optimism of that time. I didn't get much out of it, and I disagreed with some things that I might not have disagreed with if I weren't, as I am, living eighteen years after them.
Mostly they understood that giving away one's work is kind of just another way to be exploited. This should hardly be news to anyone paying any attention at all to the FOSS scene.
