Much like any software program, the source code is necessary to distribute and modify this. The central idea of copyleft is to offer users the right to copy, run, and analysis programs. Although not to add limitations.
Despite these constraints, the utilization of software can be beneficial to huge corporations and individuals. Users can easily copy the technology, modify that, and sell this, as long as that remains underneath the GNU General Public License. They are also free to use the program without showing it with anyone else.
