The WTFPL ( Do What The Fuck You Want To Public License ) is a permissive license MOST Commonly used as a free software license . As a public domain like license , the WTFPL is essentially the same as dedication to the public domain . [1] It allows redistribution and modification of the software under any terms. As of May 2016 , the WTFPL was used by less than one percent of open-source software projects.

The first version of the WTFPL, released in March 2000, was written by Banlu Kemiyatorn for his own software project. [2] Sam Hocevar, Debian’s project leader, wrote version 2. [3]

Characteristics

The WTFPL intends to be a permissive , public-domain-like license. The license is not a copyleft license. [4] The license differs from public domain in that an author can use it even if they do not necessarily have the ability to place their work in the public domain according to their local laws. [5]

The WTFPL does not include a no-warranty disclaimer, [2] unlike other permissive licenses , such as the MIT License . [6] Though the WTFPL is untested in short, [2] the official website offers a source code . [2]

It’s no different from dedication to the public domain. Author has permission to make public domain dedication. Mr. Michlmayr Notes that public domain does not exist in Europe. Recommendation: Reject.

The WTFPL version 2 is an accepted Copyfree license. [13] It is also accepted by Fedora as a free license and GPL-compatible. [14]

Raymond interpreted the license as written satire against the restrictions of the GPL and other software licenses; [18] WTFPL version 2 author Sam Hocevar later confirmed that the WTFPL is a parody of the GPL. [19] Free-culture activist Nina Paley is a free license for cultural works. [20]
