the organization's insignia for open source software. The definition was based on the Debian Free Software Guidelines, written and adapted primarily by Bruce Perens. Perens did not base his writing on the four freedoms of free software from the Free Software Foundation, which were only later available on the web. According to the OSI, Stallman initially flirted with the idea of adopting the open source term. At the end of 1990s the term "open source" gained much traction in public media and acceptance in the software industry in the context of the dotcom bubble and the open-source software driven Web 2.0. For instance, Duke University scholar Christopher M. Kelty described the Free Software movement prior to 1998 as fragmented and "the term Open Source, by contrast, sought to encompass them all in one movement". The term "open source" spread further as part of the open source movement, which inspired many successor movements including the Open content, Open-source hardware, and Open Knowledge movements. Around 2000, the success of "Open source" led several journalists to report that the earlier "Free software" term, movement, and its leader Stallman were becoming "forgotten". In response, Stallman and his FSF objected to the term "open source software" and have since campaigned for the term "free software". Due to the rejection of the term "open source software" by Stallman and FSF, the ecosystem is divided in its terminology. For example, a 2002 European Union survey revealed that 32.6% of FOSS developers associate themselves with OSS, 48% with free software, and only 19.4% are undecided or in between. As both terms "free software" and "open-source software" have their proponents and critics in the FOSS ecosystems, unifying terms have been proposed; these include "software libre" (or libre software), "FLOSS" (free/libre and open-source software), and "FOSS" (or F/OSS, free and open-source software). FOSS and F/OSS The first known use of the phrase free open-source software (in short FOSS or seldom F/OSS) on Usenet was in a posting on March 18, 1998, just a month after the term open source itself was coined. In February 2002, F/OSS appeared on a Usenet newsgroup dedicated to Amiga computer games. In early 2002, MITRE used the term FOSS in what would later be their 2003 report Use of Free and Open Source Software (FOSS) in the U.S. Department of Defense. The European Union's institutions later also used the FOSS term while before using FLOSS,
