The Wikimedia Foundation, the non-profit organization behind Wikipedia, has faced a setback in its legal battle against the UK’s Online Safety Act. On August 11, 2025, London’s High Court dismissed the Foundation’s challenge to certain provisions of the Act, which it argued could impose stringent requirements on the platform.
The Online Safety Act, enacted in 2023, aims to protect children and eliminate illegal content online. It introduces a “Category 1″ designation for major online platforms, imposing rigorous obligations such as verifying the identities of users and contributors. The Wikimedia Foundation contended that these requirements would disrupt Wikipedia’s operations and compromise user privacy.
Judge Jeremy Johnson, presiding over the case, dismissed the Foundation’s claims but noted that future legal challenges could be pursued if the UK’s communications regulator, Ofcom, improperly classifies Wikipedia as a Category 1 service. He emphasized that the ruling did not grant Ofcom or the government unrestricted authority to interfere with Wikipedia’s operations.
In response to the ruling, the Wikimedia Foundation expressed disappointment but welcomed the court’s cautionary remarks regarding potential overreach by UK authorities. The Foundation highlighted concerns that the Act’s provisions could expose volunteer editors to risks such as data breaches and legal actions, particularly in jurisdictions with less robust free speech protections.
The Online Safety Act has been a subject of controversy since its passage. Critics argue that its broad provisions could lead to censorship of legal content and infringe upon free speech rights. Supporters, including UK government officials, maintain that the law is essential for safeguarding children and removing harmful online material.
The Wikimedia Foundation’s legal challenge underscores the ongoing tension between regulatory efforts to enhance online safety and the need to preserve the open, collaborative nature of platforms like Wikipedia. The outcome of this case may have significant implications for how online platforms operate within the UK’s regulatory framework.
