In the 1970s, AT&T needed a lot of specialized, custom-written computer software to run its business. The company was forbidden to compete in the computer industry, so it could not sell this software. Instead, AT&T licensed its software and the related source code to universities for nominal sums. Universities saved money by using this software instead of commercial equivalents with pricey licenses, and university students got access to this nifty technology and could learn how everything worked.
There is no toll-free number to call and no vendor to guide you. No, you may not speak to the manager of the support team. There isn’t one. The management is you. Many commercial operating systems conceal their inner workings, and the only access you get is through the programs, application programming interfaces (APIs), and application binary interfaces (ABIs) they provide. If you want to learn more about how your operating system works, you can’t (unless you reverse-engineer it). When something breaks, you either live with it or pay the vendor to solve the problem.
