A free software is a bit of computer code that can be used devoid of restriction by the initial users or by someone else. This can be done by copying this software or modifying it, and sharing this in various ways.
The software freedom movement was started in the 1980s by simply Richard Stallman, who was concerned that proprietary (nonfree) software constituted a form of oppression for its users and a violation with their moral privileges. He formulated a set of several freedoms with regards to software to become considered free:
1 ) The freedom to improve the software.
