The GNU Project Begins — Stallman's Free-Software Declaration

On 27 September 1983, Richard Stallman, a hacker at the MIT Artificial Intelligence Laboratory, posted a message titled "Free Unix!" to the Usenet newsgroups net.unix-wizards and net.usoft.

Starting this Thanksgiving I am going to write a complete Unix-compatible software system called GNU (for Gnu's Not Unix), and give it away free to everyone who can use it.

This was the founding declaration of the GNU Project—the moment a forty-year movement crystallised around a single conviction: that the freedom to redistribute and modify software should be defended not by philosophy alone, but by working code paired with a legal framework.

Why Stallman Was Angry

The MIT AI Lab of the 1970s was the symbolic centre of hacker culture. Programmers shared a PDP-10, read each other's source, and traded modifications. The premise was unstated but firm: code is a form of knowledge, and knowledge is to be shared.

Two events broke that premise for Stallman.

The Symbolics fission (1979-1982). Members of the MIT AI Lab left to commercialise the Lisp Machine, taking internal code with them as trade secrets. The flow of shared source stopped. The hacker community fractured.

The printer-driver incident. Stallman tried to modify a driver for a new Xerox printer and discovered the source code was available only under an NDA. The right to fix the bug in front of him had been taken away by the legal construct of corporate ownership. This was, in his telling, the decisive moment.

In 1983 Stallman resigned from MIT to focus on GNU—partly to deny MIT any future claim of intellectual property over the GNU code.

The GNU Manifesto (1985)

In March 1985, Stallman published the GNU Manifesto in Dr. Dobb's Journal, formalising the four freedoms of free software:

1. Run the programme for any purpose
2. Study the source and understand how it works
3. Redistribute copies
4. Modify and redistribute the modified version

The word "free" here means "freedom", not "free of charge"—"free as in speech, not as in beer", as Stallman likes to put it.

The same year, he founded the Free Software Foundation (FSF) to serve as the legal and financial vessel of the GNU project.

The GPL — Freedom Encoded as Licence

Philosophy alone could not prevent companies from absorbing GNU code, modifying it, and shipping it as closed binaries. Stallman engineered a legal mechanism.

Copyleft inverts copyright. By writing into the licence the condition that any redistribution must be on the same terms, copyleft makes derivative works inherit the freedom as a matter of contract.

• GPLv1 (1989) — first unified GNU General Public License
• GPLv2 (1991) — required source availability whenever binaries were distributed; tightened patent language
• GPLv3 (2007) — addressed "tivoisation" (locking down hardware to deny the user freedom over modified code); strengthened patent provisions further

The GPL is sometimes called "viral" because derivatives must remain GPL. That property is precisely what makes it a legal shield for the open commons.

GNU/Linux — A Fusion by Accident

By the early 1990s, the GNU project had completed nearly the entire UNIX userland: compiler (GCC), editor (Emacs), shell (bash), the core utilities. What it lacked was a working kernel—the GNU Hurd's microkernel design proved hard to finish.

In 1991, Linus Torvalds in Finland released the Linux kernel. The following year, Torvalds relicensed Linux under GPLv2. The GNU userland and the Linux kernel snapped together. GNU/Linux existed as a fully functioning free operating system.

Stallman still insists the system should be called "GNU/Linux" rather than "Linux". The wider industry mostly does not. As a technical matter, however, much of the binary on a typical Linux distribution traces to the GNU project.

Where the 1983 Post Lives Today

The terrain forty years on:

• Cloud infrastructure — most VMs on AWS, Azure, and GCP are Linux, which is to say GNU/Linux
• Android — Linux kernel plus a great deal of GPL-licensed plumbing
• Containers and Kubernetes — built on GPL'd ancestors
• TiVo and locked-down embedded devices — the immediate practical reason for GPLv3
• AI training data — GPL-licensed source code is at the centre of ongoing debate over what may legally be used to train models

The invention the GNU project gave the world—securing the freedom of code through licence—became the model for the Apache License, the BSD licences, MIT, and Creative Commons. Stallman's 1983 Usenet post was not the announcement of a personal project. It was the first architectural drawing for the legal and economic structure that governs code as a public good.
