Uses of the MIT License Because the MIT License is not copyrighted, other groups can elect to modify the MIT License to suit their own needs. For example, the Free Software Foundation uses a license identical to the MIT License for its ncurses library, except for the addition of this text: The Free Software Foundation logo The Free Software Foundation (FSF) is a non-profit organization founded in October 1985 by Richard Stallman to support the free software movement (free as in freedom), and in particular the GNU project. ...

According to the Free Software Foundation's license list [1], the MIT license is more accurately called the X11 license, because MIT has many licenses for software. However, the Open Source Initiative refers to it as the MIT License, as do most others. Still notice that MIT and X11 Licenses are not the same. The "MIT License" is an identical match to the "Expat License" while the "MIT X Window System License" (or X11) slightly differs from the license commonly known as "MIT license".

Comparison to other licenses The MIT License is most similar to the 3-clause BSD license, which is essentially different only in the fact that it contains a notice prohibiting the use of the name of the copyright holder in promotion. The 4-clause BSD license also includes a clause requiring all advertising of the software to display a notice; the MIT License has never had this clause. The MIT license, however, more explicitly states the rights given to the end-user, including the right to use, copy, modify, merge, publish, distribute, sublicense, and/or sell the software. The BSD license is a permissive license and is one of the most widely used free software licenses. ...
