The WTFPL (Do What the Fuck You Want to Public License) is a permissive way of licensing intellectual property rights, most commonly used as a permissive free software license. It is essentially no different from dedication to the public domain. The original Version 1.0 license, released March 2000, was written by Banlu Kemiyatorn who used it for Window Maker artwork. Sam Hocevar, a French programmer who was the Debian project leader from 17 April 2007 to 16 April 2008, wrote version 2.0. It allows for redistribution and modification of the software under any terms – licensees are encouraged to "do what the fuck [they] want to". The license was approved as a GPL-compatible free software license by the Free Software Foundation.
The text of the license:
DO WHAT THE FUCK YOU WANT TO PUBLIC LICENSE Version 2, December 2004 Copyright (C) 2004 Sam Hocevar <firstname.lastname@example.org> Everyone is permitted to copy and distribute verbatim or modified copies of this license document, and changing it is allowed as long as the name is changed. DO WHAT THE FUCK YOU WANT TO PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. You just DO WHAT THE FUCK YOU WANT TO.
The WTFPL is rarely used, at least by name, but some software has been released under it. The license can also be applied to artwork and written material. Freecode, an index of free software, includes a specific category for WTFPL software and artwork, containing 37 entries as of January 2013[update], of which two are authored by Sam Hocevar, the author of version 2.0 of the license. Potlatch, an online editor of the OpenStreetMap project, as well as its more recent equivalent iD, are released under the WTFPL.
