In contrast to what the Free Software Foundation calls free software, the author of freeware usually restricts the rights of the user to use, copy, distribute, modify, make derivative works, or reverse engineer the software.[2][3][4][5] The software license may impose additional usage restrictions;[6] for instance, the license may be "free for private, non-commercial use" only,[citation needed] or usage over a network, on a server, or in combination with certain other software packages may be prohibited.[4][5] Restrictions may be required by license or enforced by the software itself; e.g., the package may fail to function over a network.[citation needed]
