Since his departure in 2002, Sanger has been
critical of Wikipedia, its policies and administrators, and the
Wikimedia Foundation. In 2015,
Vice referred to Sanger as "Wikipedia's Most Outspoken Critic". In April 2007, Sanger stated Wikipedia was "still quite useful and an amazing phenomenon" but he had "come to the view that it is also broken beyond repair" with a range of problems "from serious management problems, to an often dysfunctional community, to frequently unreliable content, and to a whole series of scandals". In September 2009, Sanger said from early on the activities of trolls on the website "was a real problem, and Jimmy Wales absolutely refused to do anything about it". Sanger described Wales as being a "fraud" and "liar" over the issue of who created Wikipedia. Wales responded to a query about the feud between the two men, stating: "I think very highly of Larry Sanger, and think that it is unfortunate that this silly debate has tended to overshadow his work." In a November 2015 interview with Zachary Schwartz for
Vice, Sanger expanded on his experiences with trolls on Wikipedia during the site's initial growth: "It was kind of stressful. I think it stressed out my wife more than me. The idea that there were people who were abusing me online just bothered her greatly." Sanger equated the trolls with modern-day
social justice warriors (SJWs). In March 2014, Sanger stated that "In some fields and some topics, there are groups who 'squat' on articles and insist on making them reflect their own specific biases. There is no credible mechanism to approve versions of articles." In December 2015, Sanger said that "Wikipedia itself might be thought to be committed to such a completely international neutrality, and in places, its policies have seemed to hold it to that utopian ambition. But of course it cannot be and it is not. The
English Wikipedia's articles about science most clearly betray its Western and especially Anglo-American provenance, and articles about, for example, philosophy are mostly about
Western philosophy. I see nothing really wrong with that." Sanger also said that "My teenage ire at shamefully biased writers and editors found expression in Nupedia's neutrality policy, which in turn became Wikipedia's", calling himself "a zealot for neutrality". In December 2017, Sanger called Wikipedia's article on
intelligent design "appallingly biased". In a May 2019 interview with Sophie Foggin of
150Sec, regarding the website's neutrality, Sanger said: "Wikipedia has long since decided to turn the other cheek when influential editors make articles speak with one point of view, when they dismiss unpopular views, or when they utterly fail to do justice to alternative approaches to a topic." Sanger also stated that Wikipedia "never did come up with a good solution" for "how to rein in the bad actors so that they did not ruin the project for everyone else" and that "Wikipedia is a broken system as a result". In a blog post in May 2020, Sanger described Wikipedia as "badly biased" and as favoring left-wing and liberal politics. In his opinion, portions of the
Donald Trump Wikipedia article are "unrelentingly negative", while the
Barack Obama article "completely fails to mention many well-known scandals". He listed other topics he argued are presented with a liberal and left-wing bias, including the topics on
Hillary Clinton,
abortion,
drug legalization, religion, and
LGBT adoption. In particular, Sanger said that Wikipedia, in describing many of Trump's statements as "false", established the website's biases. Sanger commented in the blog post: "It is time for Wikipedia to come clean and admit that it has abandoned NPOV (i.e., neutrality as a policy)." Regarding Wikipedia's current neutrality policy, Sanger said that "it endorses the utterly bankrupt canard of journalistic '
false balance', which is directly contradictory to the original neutrality policy. As a result, even as journalists turn to opinion and activism, Wikipedia now touts controversial points of view on politics, religion, and science". In a February 2021 interview with
Fox News, Sanger stated that Wikipedia's "ideological and religious bias is real and troubling, particularly in a resource that continues to be treated by many as an unbiased reference work". In a February 2021 interview with
Carrie Sheffield on
Pluto TV, Sanger criticized Wikipedia's coverage of
socialism, saying that "when schoolkids go, and they look up answers to questions about the meaning of 'socialism' ... they're going to find an explanation that completely ignores any conservative, libertarian, or critical treatment of the subject", "And that's really problematic. That's not education. That's propaganda." He argued that Wikipedia was originally "committed to neutrality" until "about 10 years ago" when "liberals or leftists made their march through the institutions ... and basically took [Wikipedia] over", adding that "They started getting rid of citations from conservative sources, even conservative sources that were cited in order to explain the conservative point of view. At least in some cases, that was the case, and more and more, certain points of view were castigated and labeled". When asked about Wikipedia's reaction to his criticism, Sanger said that "They ignore me" and that "They don't care what I say, and the feeling is mutual." In a July 2021 interview with Freddie Sayers of
LockdownTV, Sanger opined that Wikipedia is not trustworthy and that its contributors have a left-leaning bias. He further adds that since Wikipedia encourages the use of
secondary sources instead of
primary sources, Wikipedia's content is heavily influenced by coverage from center-left-wing media outlets, saying that "You can't cite the
Daily Mail at all. You can't cite
Fox News on socio-political issues either. It's banned. So what does that mean? It means that if a controversy does not appear in the mainstream center-Left media, then it's not going to appear on Wikipedia." Despite having a neutrality policy, he says that the viewpoint of Wikipedia articles represent the consensus viewpoints and that users are prohibited from adding counter-arguments to established views, which would help create more neutral articles. He argued that Wikipedia can give a "reliably establishment point of view on pretty much everything" and that "if only one version of the facts is allowed then that gives a huge incentive to wealthy and powerful people to seize control of things like Wikipedia in order to shore up their power. And they do that." In an August 2021 interview with
The Sunday Times of London, Sanger objected to Wikipedia's description of
alternative medicines, such as
homeopathy, as "
pseudoscience". He believed such a definition lacked true neutrality. Sanger also argued that "If you don't kowtow to the right people, you won't even be allowed to participate." Of Wikipedia as a whole, he said: "I advise against using it, even to conscientious students." Sanger expressed support for a proposal by the conservative think tank
Heritage Foundation to
dox and "target" Wikipedia editors they consider to be anti-Semitic, saying, "There does, of course, need to be some accountability for Wikipedia editors. For one thing, admins and those with significant authority in the system should be as easily
named and shamed as any ordinary journalist". In September 2025, Sanger published a list of proposed changes to Wikipedia titled "
The Nine Theses" on his blog and his Wikipedia user page. Sanger was interviewed about his critiques on the
Tucker Carlson podcast, where he commented on what he saw as the degrading of neutrality policies and the "blacklisting" of certain conservative sources. He also claimed that intelligence agencies like the
CIA may have influenced some direction or content on Wikipedia. Sanger's proposals were received well by members of the
Republican party and
second Trump administration, including
David Sacks and
Elon Musk, with the latter announcing
Grokipedia the same day he shared and praised Sanger's proposals. Sanger said he felt it was his "civic duty" to report the images. Critics accused Sanger of having an ulterior motive for reporting the images, noting he was still in charge of the faltering Citizendium project and said that publicizing the accusations was unnecessary. In 2012, Sanger told
Fox News that he worked with NetSpark to get them to donate or heavily discount its pornographic image
filtering technology for use on Wikipedia. He said that NetSpark attempted to contact the
Wikimedia Foundation in 2012 but received no response. In a subsequent interview with
TechCrunch TV, Sanger criticized Wikipedia for containing too much pornography that children could access and said that he did not regret leaving Wikipedia. ==Later activities==
