Free Software Culture
Gratis versus libre is the distinction between "for zero price" (gratis) and "freedom" (libre). Gratis appears in many English dictionaries, including the Oxford English Dictionary. However, libre does so less commonly, and no English adjective signifies "liberty" exclusively and as distinct from "at no monetary cost". This distinction is often important in dealing with laws concerning the use of information, such as copyright and patents. The terms are often used in the free software and open source communities, as well as the broader free culture movement, to categorize computer programs according to the licenses and legal restrictions that cover them. Both this expression and the term gratis are used to distinguish freeware (gratis software) from free (libre) software.
Proprietary software is software covered by copyright, patent, or trademark law or controlled by a single legal entity. When the term is used by Richard Stallman, it is pejorative[1][2]. The term is often contrasted with open source, and in this situation, the pejorative connotation isn't there.[3][4][5]
Well known examples of proprietary software include Microsoft Windows, RealPlayer, iTunes, Adobe Photoshop, Mac OS X, WinZip and some versions of Unix.
Shareware, like freeware, is proprietary software available at zero price, but differs in that it is free only for a trial period, after which some restriction is imposed or it is completely disabled. Proprietary software which is no longer marketed by its owner and is used without permission by users is called abandonware and may include source code. Some abandonware has its source code placed in the public domain either by its author or copyright holder and is therefore free software, not proprietary software.
The Free Software Foundation (FSF) is a non-profit corporation founded by Richard Stallman on 4 October 1985 to support the free software movement, a copyleft-based movement which aims to promote the universal freedom to distribute and modify computer software without restriction. The FSF is incorporated in Massachusetts, United States of America.
Copyleft is a form of licensing and may be used to modify copyrights for works such as computer software, documents, music, and art. In general, copyright law allows an author to prohibit others from reproducing, adapting, or distributing copies of the author's work. In contrast, an author may, through a copyleft licensing scheme, give every person who receives a copy of a work permission to reproduce, adapt or distribute the work as long as any resulting copies or adaptations are also bound by the same copyleft licensing scheme. A widely used and originating copyleft license is the GNU General Public License. Similar licenses are available through Creative Commons—called Share-alike.
