Freedom from such restrictions is central to the concept, with the opposite of free software being proprietary software (a distinction unrelated to whether a fee is charged). The usual way for software to be distributed as free software is for the software to be licensed to the recipient with a free software license (or be in the public domain), and the source code of the software to be made available (for a compiled language).
To help distinguish libre (freedom) software from gratis (zero price) software, Richard Stallman, founder of the free software movement, developed the following explanation: "Free software is a matter of liberty, not price. To understand the concept, you should think of 'free' as in 'free speech', not as in 'free beer'". More specifically, free software means that computer users have the freedom to cooperate with whom they choose, and to control the software they use. The GNU Manifesto contains language that gives evidence of Stallman's initial confusion with the usage.
Most free software is distributed online without charge, or off-line at the marginal cost of distribution, but this is not required, and people may sell copies for any price. Thus, free software is entirely compatible with commercial software: a prohibition on selling the software would be a restriction failing the free software definition.
The capitalized term "Open source" is attached to a definition originally created in 1998 from Debian's free software guidelines. While most open source software is also free software and vice-versa, this is not always the case.
The free BSD-based operating systems, such as FreeBSD, OpenBSD, and NetBSD, use a similar definition of free software, but they differ in interpretation about copyleft. Users of th
