Free as in Freedom. Richard Stallman’s Crusade for Free Software

Through such vigilance, hackers managed to keep the AI Lab’s machines security-free. Over at the nearby MIT Laboratory for Computer Sciences, however, security-minded faculty members won the day. The LCS installed its first password-based system in 1977. Once again, Stallman took it upon himself to correct what he saw as ethical laxity. Gaining access to the software code that controlled the password system, Stallman implanted a software command that sent out a message to any LCS user who attempted to choose a unique password. If a user entered “starfish”, for example, the message came back something like:

I see you chose the password “starfish”. I suggest that you switch to the password “carriage return”. It’s much easier to type, and also it stands up to the principle that there should be no passwords.10

Users who did enter “carriage return”-that is, users who simply pressed the Enter or Return button, entering a blank string instead of a unique password-left their accounts accessible to the world at large. As scary as that might have been for some users, it reinforced the hacker notion that Institute computers, and even Institute computer files, belonged to the public, not private individuals. Stallman, speaking in an interview for the 1984 book Hackers, proudly noted that one-fifth of the LCS staff accepted this argument and employed the blank-string password.11

Stallman’s null-string crusade would prove ultimately futile. By the early 1980s, even the AI Lab’s machines were sporting password-based security systems. Even so, it represents a major milestone in terms of Stallman’s personal and political maturation. To the objective observer familiar with Stallman’s later career, it offers a convenient inflection point between the timid teenager afraid to speak out even on issues of life-threatening importance and the adult activist who would soon turn needling and cajoling into a full-time occupation.

In voicing his opposition to computer security, Stallman drew on many of the forces that had shaped his early life: hunger for knowledge, distaste for authority, and frustration over hidden procedures and rules that rendered some people clueless outcasts. He would also draw on the ethical concepts that would shape his adult life: communal responsibility, trust, and the hacker spirit of direct action. Expressed in software-computing terms, the null string represents the 1.0 version of the Richard Stallman political worldview-incomplete in a few places but, for the most part, fully mature.

Looking back, Stallman hesitates to impart too much significance to an event so early in his hacking career. “In that early stage there were a lot of people who shared my feelings”, he says. “The large number of people who adopted the null string as their password was a sign that many people agreed that it was the proper thing to do. I was simply inclined to be an activist about it”.

Stallman does credit the AI Lab for awakening that activist spirit, however. As a teenager, Stallman had observed political events with little idea as to how a single individual could do or say anything of importance. As a young adult, Stallman was speaking out on matters in which he felt supremely confident, matters such as software design, communal responsibility, and individual freedom. “I joined this community which had a way of life which involved respecting each other’s freedom”, he says. “It didn’t take me long to figure out that that was a good thing. It took me longer to come to the conclusion that this was a moral issue”.

Hacking at the AI Lab wasn’t the only activity helping to boost Stallman’s esteem. During the middle of his sophomore year at Harvard, Stallman had joined up with a dance troupe that specialized in folk dances. What began as a simple attempt to meet women and expand his social horizons soon expanded into yet another passion alongside hacking. Dancing in front of audiences dressed in the native garb of a Balkan peasant, Stallman no longer felt like the awkward, uncoordinated 10-year-old whose attempts to play football had ended in frustration. He felt confident, agile, and alive. For a brief moment, he even felt a hint of emotional connection. He soon found being in front of an audience fun, and it wasn’t long thereafter that he began craving the performance side of dancing almost as much as the social side.
