Software freedom is the freedom to run the program as you wish, for any purpose, to study how the program works, and change it, to redistribute copies and your modified versions so you can help others.
When Free Software Depends on Nonfree - GNU Project - Free Software Foundation
When a program is free software (free as in freedom), that means it gives users the four freedoms, so that they control what the program does. In most cases, that is sufficient for the program's distribution to be ethical; but not always. There are additional problems that can arise in specific circumstances. This article describes a subtle problem, where upgrading the free program requires using a nonfree program.
Freedom Isn't Free
An inquiry into the failure of the free software movement, and a proposal for recovering its radical soul.
Decoding Liberation: The Promise of Free and Open Source Software
Choice Outstanding Academic Title Software is more than a set of instructions for computers: it enables (and disables) political imperatives and policies. Nowhere is the potential for radical social and political change more apparent than in the practice and movement known as
What is Free Software? - GNU Project - Free Software Foundation
Since 1983, developing the free Unix style operating system GNU, so that computer users can have the freedom to share and improve the software they use.
Why Open Source Misses the Point of Free Software - GNU Project - Free Software Foundation
The terms “free software” and “open source” stand for almost the same range of programs. However, they say deeply different things about those programs, based on different values. The free software movement campaigns for freedom for the users of computing; it is a movement for freedom and justice. By contrast, the open source idea values mainly practical advantage and does not campaign for principles. This is why we do not agree with open source, and do not use that term.
Sorting out the Ethical Licensing Mess
Software developers who give the world, for free, usage rights to the code they write often use open source licenses to make this gift legally explicit. These free usage rights (and then some) are …
Unlicense Yourself: Set Your Code Free
An initiative to help software developers waive their copyright and dedicate their work to the public domain by offering a standard template and process for disclaiming copyright interest in software, both for original authorship and for contributions.
History of free and open-source software
The history of free and open-source software begins at the advent of computer software in the early half of the 20th century. In the 1950s and 1960s, computer operating software and compilers were delivered as a part of hardware purchases without separate fees. At the time, source code—the human-readable form of software—was generally distributed with the software, providing the ability to fix bugs or add new functions. Universities were early adopters of computing technology. Many of the modifications developed by universities were openly shared, in keeping with the academic principles of sharing knowledge, and organizations sprung up to facilitate sharing.

Chapter 1. Introduction
Free software — open source software[3] — has become the backbone of modern information technology. It runs on your phone, on your laptop and desktop computers, and in embedded microcontrollers for household appliances, automobiles, industrial machinery and countless other devices that we too often forget even have software. Open source is especially prevalent on the servers that provide online services on the Internet. Every time you send an email, visit a web site, or call up some information on your smartphone, a significant portion of the activity is handled by open source software.
Why We Can't Have Nice Software - Andrew Kelley
The problem with software is that it's too powerful. It creates so much wealth so fast that it's virtually impossible to not distribute it.
Pluralistic: The (other) problem with automatic conversion of free software to proprietary software (23 Apr 2026) – Pluralistic: Daily links from Cory Doctorow
Here's an interesting stunt: a project called Malus.sh will take your money, and in exchange, it will ingest any free/open source code you want, refactor that code using an LLM, and spit out a "clean room" version that is freed from all the obligations imposed by the original project's software license:
