Free Software Movement

Motivation

The software desenvolvedores in the decade of 70 frequently they shared their programs in a similar way to the beginnings of the free software. In the end of the same decade, the companies began to impose restrictions to the users with the use of contracts of software license.

In 1983, Richard Stallman began the project GNU, and in October of 1985 it founded Free Software Foundation (FSF). Stallman introduced the concepts of free software and copyleft, which were specifically developed to guarantee that the users’ freedom was preserved.

Ideology: the differences between Free Software and Open Code

Many defenders of the free software argue that the freedom is valuable not only of the technical point of view, but also under the optics of the morals and ethics.

It is in this aspect that the movement of free (headed by FSF) software stands out of the movement of open (headed by OSI) code, that it emphasizes the technical superiority in relation to software proprietor, at least in potential.

The defenders of the open (also known as Open source in English) code argue regarding the pragmatic virtues of the free software instead of the moral subjects. The basic disagreement of the movements is in the speech.

While the focus of the movement headed by FSF calls the attention for values moral, ethical, rights and freedom, the movement headed by OSI defends a more pleasant speech to the companies.

With that, the movement of free software condemns the use and software proprietor’s development, while the movement of open code is connivent with software proprietor’s development.

The official definitions of free software and of open code they are the same, however written in different ways. OSI defines the open code using the definition Debian of free software, that is just a detalhamento of the 4 freedoms of FSF. This way every software of open code is also a free software.

The movement free software used to take a position on works that are not softwares and their respective documentations, but some defenders of the free software believe that other works that serve to a practical purpose should also be free (see Free content).

For the Movement of the free software, that it is a social movement, it is not ethical to arrest scientific knowledge, that it should always be available, for like this to allow the humanity’s evolution.

Already the movement for the Open Code, that is a movement more returned to the market, it nails that the software of that type brings several technical and economical advantages. The second appeared to take the companies adopt her/it the model of development of free software.

As the difference between the movements “Free Software” and “Open Code” is just in the (Free / Livery and Open Source Software) argument on behalf of the same softwares, it is common that those groups join in several situations or that are mentioned of a form agregadora through the acronym “FLOSS.”

Related movements

Inspired in GPL and in the proposals of the movement of the free software, a repository of public licenses was created, called Creative Commons, whose we have if they apply to varied creative works, as creations artistic colaborativas, texts and software. However most of these licenses is not recognized as really free for FSF and for the movement of free software.

The free software is inserted in a wider context where the information (of all of the types, not just software) is considered a legacy of the humanity and it should be free (vision this that is shocked directly to the traditional concept of intellectual property). Coerentemente, many of the people that contribute to the movements of Open Knowledge. I move of the free software, sites Wiki, Creative Commons, etc. . they are the scientific community’s part.

Scientists are accustomed to work with processes of mutual (or for equal) revision and the developed content is joined to the global scientific knowledge. Although cases exist where the patents of products related to the scientific work are applied, the pure science, in general, is free.
