The head of the Wikimedia Foundation, the nonprofit that runs Wikipedia and related websites, has unexpectedly resigned. Lila Tretikov said Thursday in a statement that "with great respect," she has tendered her resignation as executive director of the Wikimedia Foundation. "The Board tasked me with making changes to serve the next generation and ensure our impact in the future," Tretikov wrote. "Driving these changes has been challenging, and I have always appreciated the open and honest discourse we have had along the way."
Tretikov's resignation comes at a time of unprecedented tension between the community of editors and the Board of Trustees that runs the Wikimedia Foundation. Last month, a newly appointed board member stepped down after hundreds of editors signed a "vote of no confidence."
Following that resignation, a second uproar arose over a $250,000 grant from the Knight Foundation to help Wikimedia Foundation create a "knowledge engine" that would improve search. Some activist Wikipedia editors had been asking to see documentation about the Knight Foundation grant for several months, but Wikimedia was not forthcoming with the details.
Earlier this month, documents related to the grant were leaked to and published by The Signpost, Wikipedia's online newspaper. In a special report, The Signpost published the 13-page grant agreement and ran an article asserting that the "Knowledge Engine" would be, contrary to statements by Jimmy Wales and other board members, some type of generalized Internet search engine. "The presentation contrasts the ideals and motivations of commercial search engines—they 'highlight paid results, track users' internet habits, sell information to marketing firms'—with those of 'Wikipedia Search', which will be private, transparent, and globally representative," wrote The Signpost. "It repeatedly stressed that "no other search engines carry these ideals."

Those revelations caused more consternation amongst editors. Some worried that the Foundation was trying to "compete with Google," working on a general-purpose search engine that should be seen as "out of scope" for a nonprofit dedicated to providing free knowledge. Other editors saw the project as a conflict of interest for Wikipedia founder Jimmy Wales, whose for-profit company Wikia could benefit from having Wikipedia spend large amounts of research money on search. Wikia tried to create an open source search engine but abandoned it in 2009.
