Proprietary software is Computer software on which the producer has set restrictions on use private modification copying, or republishing.
According to the Free Software Foundation, the MIT License is more accurately called the X11 license, since MIT has used many licenses for software and the license was first drafted for the X Window System. The Free Software Foundation ( FSF) is a Non-profit corporation founded by Richard Stallman on 4 October 1985 to support the Free software movement [1]
Software packages that use the MIT License include Expat, PuTTY, Mono development platform class libraries, Ruby on Rails, Twisted, Lua 5.0 onwards and the X Window System, for which the license was written. Expat is a stream -oriented XML 10 parser library, written in C. Putty is a generic term for a plastic material similar in texture to Clay or Dough typically used in domestic construction and repair as a sealant or filler Mono is a project led by Novell (formerly by Ximian) to create an Ecma standard compliant. Ruby on Rails is an Open source Web application framework for the Ruby programming language. Twisted is an event-driven network programming Framework written in Python and licensed under the MIT License. In Computing, Lua (ˈluːa LOO-ah is a lightweight, reflective, imperative and procedural Programming language,
Some software packages dual license their products under the MIT License, such as older versions of the cURL library, which allowed recipients to choose either the Mozilla Public License or the MIT License. Dual-licensing is the practice of distributing Software under two different sets of terms and conditions cURL is a Command line tool for transferring files with URL syntax. The Mozilla Public License (MPL is a free and Open source Software license.

Modified versions of the license
The license can be modified to suit particular needs. For example, the Free Software Foundation agreed in 1998 to use a modified MIT License for ncurses, which adds this clause:[2]
- Except as contained in this notice, the name(s) of the above copyright holders shall not be used in advertising or otherwise to promote the sale, use or other dealings in this Software without prior written authorization. The Free Software Foundation ( FSF) is a Non-profit corporation founded by Richard Stallman on 4 October 1985 to support the Free software movement Year 1998 ( MCMXCVIII) was a Common year starting on Thursday (link will display full 1998 Gregorian calendar) ncurses is a programming library providing an API, allowing the programmer to write Text user interfaces in a terminal-independent manner
The XFree86 Project uses a modified MIT License for XFree86 version 4. XFree86 is an implementation of the X Window System. It was originally written for Unix-like Operating systems on IBM PC compatibles and is now 4 onward. The license includes a clause that requires attribution in software documentation. [3] The Free Software Foundation contends that this addition is incompatible with the version 2 of the GPL, but compatible with version 3. The Free Software Foundation ( FSF) is a Non-profit corporation founded by Richard Stallman on 4 October 1985 to support the Free software movement [4]
- The end-user documentation included with the redistribution, if any, must include the following acknowledgment: "This product includes software developed by The XFree86 Project, Inc (http://www. xfree86. org/) and its contributors", in the same place and form as other third-party acknowledgments. Alternately, this acknowledgment may appear in the software itself, in the same form and location as other such third-party acknowledgments.
Comparison to other licenses
The MIT License is similar to the 3-clause "modified" BSD license, except that the BSD license contains a notice prohibiting the use of the name of the copyright holder in promotion. BSD licenses represent a family of Permissive free software licences. This is sometimes present in versions of the MIT License, as noted above.
The original BSD license also includes a clause requiring all advertising of the software to display a notice crediting its authors. This "advertising clause" (since disavowed by UC Berkeley[5]) is only present in the modified MIT License used by XFree86. XFree86 is an implementation of the X Window System. It was originally written for Unix-like Operating systems on IBM PC compatibles and is now
The MIT License states more explicitly the rights given to the end-user, including the right to use, copy, modify, merge, publish, distribute, sublicense, and/or sell the software. Economics and Commerce define an end-user as the person who uses a product.
A 2-clause BSD-style license, found in software such as Apple Inc.'s WebKit (though most of WebKit is under the LGPL) is essentially identical to the MIT License, as it does not contain an advertising clause. Apple Inc, ( formerly Apple Computer Inc, is an American Multinational corporation with a focus on designing and manufacturing Consumer electronics WebKit is an Open source Application framework that provides a foundation upon which to build a Web browser. The GNU Lesser General Public License (formerly the GNU Library General Public License) or LGPL is a Free software license published by the Free Software
Also similar in terms is the ISC license, which has a simpler language. The ISC licence is a Permissive free software licence written by the Internet Systems Consortium (ISC
The University of Illinois/NCSA Open Source License combines text from both the MIT and BSD licenses; the license grant and disclaimer are taken from the MIT License. The University of Illinois/NCSA Open Source License is a Permissive free software licence, based on the MIT/X11 and BSD licenses
