The quote seems to be from Chapter 5, "A brief treatise on the moral grounds of economic relations", page 96. It comes at the end of a paragraph giving examples of how almost everyone follows the principle of "from each according to their abilities, to each according to their needs" if they are collaborating on some common project.
Just before the Apple Computers example, Graeber writes "The greater the need to improvise, the more democratic the cooperation tends to become. Inventors have always understood this, start-up capitalists frequently figure it out, and computer engineers have recently rediscovered the principle: not only with things like freeware, which everyone talks about, but even in the organization of their businesses."
