GNU Project instance of free software project
Free software
The GNU project uses software that is free for users to copy, edit, and distribute. It is free in the sense that users can change the software to fit individual needs. The way programmers obtain the free software depends on where they get it. The software could be provided to the programmer from friends or over the Internet, or the company a programmer works for may purchase the software.Copyleft
Copyleft is what helps maintain free use of this software among other programmers. Copyleft gives the legal right to everyone to use, edit, and redistribute programs or programs' code as long as the distribution terms do not change. As a result, any user who obtains the software legally has the same freedoms as the rest of its users do.
The GNU Project and the Free Software Foundation sometimes differentiate between "strong" and "weak" copyleft. "Weak" copyleft programs typically allow distributors to link them together with non-free programs, while "strong" copyleft strictly forbids this practice. Most of the GNU Project's output is released under a strong copyleft, although some is released under a weak copyleft or a lax, push-over free software license.
