TheWTFPL is apermissivefree software license.[1] As apublic domain like license, the WTFPL is essentially the same as dedication to thepublic domain.[2] It allows redistribution and modification of the work under any terms. The name is an abbreviation ofDo What The Fuck You Want To Public License.

The first version of the WTFPL, released in March 2000, was written by Banlu Kemiyatorn for his own software project.[3]Sam Hocevar,Debian's former project leader, wrote version 2.[4]

Characteristics

[edit]

The WTFPL intends to be apermissive, public-domain-like license. The license is not acopyleft license.[1] 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][failed verification]

The WTFPL does not include a no-warranty disclaimer, unlike other permissive licenses, such as theMIT License.[6] Though the WTFPL is untested in court, the official website offers a disclaimer to be used in softwaresource code.[3][better source needed]

Terms

[edit]

Version 2

Reception

[edit]

Usage

[edit]

The WTFPL is not in wide use amongopen-source software projects; according toBlack Duck Software, the WTFPL is used by less than one percent of open-source projects.[7]Examples include theOpenStreetMapPotlatch online editor,[8] the video gameLiero (version 1.36),[9] yalu102[10] andMediaWiki extensions.[11] More than 6,000Wikimedia Commons files[12] and more than 34,000 Projects onGitHub were published under the terms of the WTFPL.[13]

Discussion

[edit]

The license was confirmed as aGPL-compatible free software license by theFree Software Foundation, but its use is "not recommended".[1] In 2009, theOpen Source Initiative chose not to approve the license as anopen-source license due to redundancy with theFair License.[2]

The WTFPL version 2 is an acceptedCopyfree license.[14] It is also accepted byFedora as a free license and GPL-compatible.[15]

Some software authors have said that the license is not very serious;[16]forks have tried to address wording ambiguity and liability concerns.[17][18] OSI founding presidentEric S. Raymond interpreted the license as written satire against the restrictions of the GPL and other software licenses;[19] WTFPL version 2 authorSam Hocevar later confirmed that the WTFPL is a parody of the GPL.[20]Free-culture activistNina Paley said she considered the WTFPL a free license for cultural works.[21]

Google does not allow its employees to contribute to projects under public domain equivalent licenses like the WTFPL (and Unlicense CC0), while allowing contributions to0BSD licensed andUS government PD projects.[22]

The author is one of those who thinks the Free Software Foundation has traduced the word 'free' by hedging the GNU General Public License about with restrictions and boobytraps in the name of 'freedom' – and he's got an issue or two with BSD as well. He is poking fun at both camps, not gently at all. His page about the WTFPL is funny-because-it's-true hilarious, and I admit that I feel a sneaking temptation to start using it myself.

The purpose of the WTFPL wording is to give more freedom than the GPL does.
