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
The WTFPL intends to be a permissive, public-domain-like license. The license is not a copyleft 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 the MIT License.[6] Though the WTFPL is untested in court, the official website offers a disclaimer to be used in software source code.[3][better source needed]

The WTFPL version 2 is an accepted Copyfree license.[14] It is also accepted by Fedora 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 president Eric S. Raymond interpreted the license as written satire against the restrictions of the GPL and other software licenses;[19] WTFPL version 2 author Sam Hocevar later confirmed that the WTFPL is a parody of the GPL.[20]Free-culture activist Nina 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 to 0BSD licensed and US government PD projects.[22]

Author has submitted license approval request -- author is free to make public domain dedication. Although he agrees with the recommendation, Mr. Michlmayr notes that public domain doesn't exist in Europe. Recommend: Reject. [...] Mr. Michlmayr did not agree with the reasons cited for possible rejection of the WFTPL license since public domain doesn't exist in Europe.

^Suder, Kuba (2011-01-15). "On Open Source licensing". Apples & Rubies (Blog). There are at least two not very serious licenses which have essentially the same meaning as public domain. I'm talking about the Beerware license and WTFPL ('Do What The Fuck You Want To' license). I really like these because they pretty well represent my opinion about the legalese bullshit that most licenses are so full of.

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.
^Sam Hocevar (2015-09-21). "Should I change the name of the WTFPL?". Programmers Stack Exchange (User comment). Retrieved 2016-07-19. The WTFPL is a parody of the GPL, which has a similar copyright header and list of permissions to modify (i.e. none), see for instance gnu.org/licenses/gpl-3.0.en.html. The purpose of the WTFPL wording is to give more freedom than the GPL does.
