Why Software Should Be Free</h3></a><div class="teasers_item"><p>The existence of software inevitably raises the question of how decisions about its use should be made. For example, suppose one individual who has a copy of a program meets another who would like a copy. It is possible for them to copy the program; who should decide whether this is done? The individuals involved? Or another party, called the “owner”? </p></div></li>

Why Schools Should Exclusively Use Free&nbsp;Software</h3></a><div class="teasers_item"><p>There are general reasons why all computer users should insist on free software: it gives users the freedom to control their own computers—with proprietary software, the computer does what the software owner wants it to do, not what the user wants it to do. Free software also gives users the freedom to cooperate with each other, to lead an upright life. These reasons apply to schools as they do to everyone. </p></div></li>

Releasing Free Software If You Work at a&nbsp;University</h3></a><div class="teasers_item"><p>In the free software movement, we believe computer users should have the freedom to change and redistribute the software that they use. The “free” in “free software” refers to freedom: it means users have the freedom to run, modify and redistribute the software. Free software contributes to human knowledge, while nonfree software does not. Universities should therefore encourage free software for the sake of advancing human knowledge, just as they should encourage scientists and other scholars to publish their work.</p></div></li>

Why Free Software Needs Free&nbsp;Documentation</h3></a><div class="teasers_item"><p>The biggest deficiency in free operating systems is not in the software—it is the lack of good free manuals that we can include in these systems. Many of our most important programs do not come with full manuals. Documentation is an essential part of any software package; when an important free software package does not come with a free manual, that is a major gap. We have many such gaps today. </p></div></li>

A rose by any other name would smell as sweet—but if you call it a pen, people will be rather disappointed when they try to write with it. And if you call pens “roses,” people may not realize what they are good for. If you call our operating system Linux, that conveys a mistaken idea of the system’s origin, history, and purpose. If you call it GNU/Linux, that conveys (though not in detail) an accurate idea. </p></div></li>

Misinterpreting Copyright&mdash;A Series of&nbsp;Errors</h3></a><div class="teasers_item"><p>Something strange and dangerous is happening in copyright law. Under the US Constitution, copyright exists to benefit users—those who read books, listen to music, watch movies, or run software—not for the sake of publishers or authors. Yet even as people tend increasingly to reject and disobey the copyright restrictions imposed on them “for their own benefit,” the US government is adding more restrictions, and trying to frighten the public into obedience with harsh new penalties.</p></div></li>

Science Must Push Copyright Aside</h3></a><div class="teasers_item"><p>It should be a truism that the scientific literature exists to disseminate scientific knowledge, and that scientific journals exist to facilitate the process.

Freedom&mdash;or Copyright</h3></a><div class="teasers_item"><p>Copyright was established in the age of the printing press as an industrial regulation on the business of writing and publishing. The aim was to encourage the publication of a diversity of written works. The means was to require publishers to get the author’s permission to publish recent writings. This enabled authors to get income from publishers, which facilitated and encouraged writing. The general reading public received the benefit of this, while losing little: copyright restricted only publication, not the things an ordinary reader could do. That made copyright arguably a beneficial system for the public, and therefore arguably legitimate. </p></div></li>

Copyleft: Pragmatic Idealism</h3></a><div class="teasers_item"><p>Every decision a person makes stems from the person’s values and goals. People can have many different goals and values; fame, profit, love, survival, fun, and freedom, are just some of the goals that a good person might have. When the goal is a matter of principle, we call that idealism.</p></div></li>

Anatomy of a Trivial Patent</h3></a><div class="teasers_item"><p>Programmers are well aware that many of the existing software patents cover laughably obvious ideas. Yet the patent system’s defenders often argue that these ideas are nontrivial, obvious only in hindsight. And it is surprisingly difficult to defeat them in debate. Why is that? </p></div></li>

Software Patents and Literary Patents</h3></a><div class="teasers_item"><p>When politicians consider the question of software patents, they are usually voting blind; not being programmers, they don’t understand what software patents really do. They often think patents are similar to copyright law (“except for some details”)—which is not the case. For instance, when I publicly asked Patrick Devedjian, then Minister for Industry in France, how France would vote on the issue of software patents, Devedjian responded with an impassioned defense of copyright law, praising Victor Hugo for his role in the adoption of copyright. (The misleading term “intellectual property” promotes this confusion—one of the reasons it should never be used.) </p></div></li>

The Danger of Software Patents</h3></a><div class="teasers_item"><p>I’m most known for starting the free software movement and leading development of the GNU operating system—although most of the people who use the system mistakenly believe it’s Linux and think it was started by somebody else a decade later. But I’m not going to be speaking about any of that today. I’m here to talk about a legal danger to all software developers, distributors, and users: the danger of patents—on computational ideas, computational techniques, an idea for something you can do on a computer. </p></div></li>

Can You Trust Your Computer?</h3></a><div class="teasers_item"><p>Who should your computer take its orders from? Most people think their computers should obey them, not obey someone else. With a plan they call “trusted computing,” large media corporations (including the movie companies and record companies), together with computer companies such as Microsoft and Intel, are planning to make your computer obey them instead of you. (Microsoft’s version of this scheme is called Palladium.) Proprietary programs have included malicious features before, but this plan would make it universal.</p></div></li>

Who Does That Server Really Serve?</h3></a><div class="teasers_item"><p>Digital technology can give you freedom; it can also take your freedom away. The first threat to our control over our computing came from proprietary software: software that the users cannot control because the owner (a company such as Apple or Microsoft) controls it. The owner often takes advantage of this unjust power by inserting malicious features such as spyware, back doors, and Digital Restrictions Management (DRM) (referred to as “Digital Rights Management” in their propaganda). </p></div></li>

Free but Shackled: The Java Trap</h3></a><div class="teasers_item"><p>If your program is free software, it is basically ethical—but there is a trap you must be on guard for. Your program, though in itself free, may be restricted by nonfree software that it depends on. Since the problem is most prominent today for Java programs, we call it the Java Trap. </p></div></li>

The JavaScript Trap</h3></a><div class="teasers_item"><p>In the free software community, the idea that nonfree programs mistreat their users is familiar. Some of us refuse entirely to install proprietary software, and many others consider nonfreedom a strike against the program. Many users are aware that this issue applies to the plug-ins that browsers offer to install, since they can be free or nonfree. </p></div></li>

That is one of the major controversies in the free software community. The idea of copyleft is that we should fight fire with fire—that we should use copyright to make sure our code stays free.

Alas, I disagree completely with the path that led him to it. He presents serious security problems as an intolerable crisis, but I’m not convinced. Then he forecasts that users will panic in response and stampede toward restricted computers (which he calls “appliances”), but there is no sign of this happening. </p></div></li>

Word attachments are annoying, but, worse than that, they impede people from switching to free software. Maybe we can stop this practice with a simple collective effort.

He recently eliminated a major weakness of the free software community, by announcing the end of his campaign to entice free software projects to use and promote his nonfree software.
