Back in college I was pretty heavily involved in the local LUG (organised events, President for a while, etc.), and it didn't take more than a few year's experience to teach me that the politics of the Free Software viewpoint might have been morally right, but were practically useless in the liberatory sense. Unless FOSS stocked away enough capital to liberate *itself*, it could never do enough to build the sort of high-level managerial systems that would allow it to compete under capitalism.
I wish I'd internalized maybe 20 years earlier that the only way free software could be liberatory, rather than merely, selfishly libertarian, is if the goals became not to secure our own freedoms, but to grant them to other people. Today almost nobody can change the software they use, and as a measurable fact almost nobody who can the change software the use does. But even so: having those choices matters; securing the fact of them, evangelizing and defending that fact, matters.
