I’d be particularly interested to learn of an argument that isn’t adequately addressed by http://www.gnu.org/gnu/why-gnu-linux.html or http://www.gnu.org/gnu/gnu-linux-faq.html.

Some of Cowie’s slides look suspiciously wrong, like referring to copyright infringement as theft (”Don’t steal music.”) conflating the philosophies of the open source and free software movements, or saying “No one can tell you no” accurately expresses software freedom. One wonders what in Friedman’s book is worth recommending, or if he’s actually giving an anti-recommendation (read it to laugh at the pro-corporatist views that fail to viably address the plight of about half a billion of the poorest people in India). But I’ll withhold judgement until I’ve heard what he has to say.
