Wikimedia warns that an adverse AI copyright decision could endanger the open web

Wikimedia’s Position in the AI Copyright Dispute

The Wikimedia Foundation filed an amicus brief on Friday in a series of high‑profile lawsuits that pit publishers such as The New York Times against OpenAI and Microsoft.

In the filing, the nonprofit says it is not taking sides but is urging courts to adopt a nuanced view of the fair‑use doctrine as it applies to large language models.

“Wikimedia is concerned that the parties’ positions in this case push for overbroad and simplified applications of the fair use doctrine,” the brief reads.

Wikimedia argues that training AI on copyrighted material should generally qualify as fair use, while the direct regurgitation of that material to end users should not.

The organization warns that a black‑and‑white ruling favoring publishers could allow copyright holders to “gatekeep” even transformative uses of their work.

Conversely, a ruling that fully favors AI developers could give companies a “green light to snub licensing terms and fragment the flow of knowledge between human authors and audiences.”

Potential Impacts on Wikipedia and the Open Web

Wikimedia stresses that Wikipedia and its sister sites are among the most critical data sources for training artificial‑intelligence and machine‑learning systems.

At the same time, the same AI services draw traffic away from Wikipedia, threatening the volunteer communities that maintain the sites.

The brief alleges that services like ChatGPT reproduce text that is freely licensed under Creative Commons but fail to honor the license’s attribution and share‑alike requirements.

Despite these concerns, the foundation acknowledges that large language models can provide valuable assistance to editors, such as detecting vandalism, flagging copyright violations, and identifying articles that need improvement.

Stephen LaPorte, a member of Wikimedia’s General Council, said, “A ruling that does not apply fair use principles carefully could threaten the sustainability of free knowledge, and stifle the development of open source technologies, ultimately impacting access to information for everyone in both cases.”

He added that Wikipedia’s collaborative model depends on a strong foundation of open and accessible human knowledge.

The Stakes of the Ongoing Litigation

The New York Times is pushing for a broader definition of fair use, alleging that OpenAI scraped its website to build training datasets without permission.

OpenAI and Microsoft contend that the use of copyrighted works in pre‑training is protected by fair use and that any “regurgitation” of text is a rare bug.

Microsoft’s September filing claimed expert analysis shows Copilot “rarely reproduces full sentences from news content used to ground the model, which it said, ‘hardly undermines the transformative purpose of LLM training.’”

Wikimedia proposes a compromise: scraping publicly available websites should not be treated as copyright infringement, and using copyrighted works to pre‑train large language models without a license should be deemed fair use.

The foundation warns that an overly simplistic court decision could either strip Wikipedia of AI‑powered tools that aid its editors or enable AI firms to bypass licensing, thereby fragmenting the open web.

Both outcomes, according to the brief, risk undermining the free‑knowledge ecosystem that underpins much of the internet’s informational infrastructure.

Stakeholders across the tech and publishing sectors are watching the cases closely, as the rulings could set precedent for how AI systems are trained on copyrighted content worldwide.

Legal analysts note that the courts’ interpretation of fair use in the context of massive, data‑hungry models will shape the balance between innovation and creators’ rights for years to come.

Wikimedia’s involvement signals that the nonprofit sees the litigation as a pivotal moment for the future of collaborative knowledge sharing.

It emphasizes that any ruling must preserve the ability of volunteers to access and improve open‑source information while still protecting legitimate copyright interests.

“A ruling that does not apply fair use principles carefully could threaten the sustainability of free knowledge,” LaPorte reiterated, underscoring the existential stakes for Wikipedia.

Why This Matters

A court decision that narrowly defines fair use for AI training could either cripple Wikipedia’s ability to leverage AI tools or allow AI firms to sidestep licensing, jeopardizing the open web’s collaborative knowledge base.
