A UK judge dismisses Wikimedia's Online Safety Act challenge over requiring Wikipedia to verify users and contributors' IDs, but says it can file new challenges
Europe is not allowed to make Internet Laws. — arstechnica.com/tech-policy/ ... Hari Kunzru / @harikunzru : There is a possible future in which the UK government ends up blocking Wikipedia to save face as the ridiculous OSA age verification provision backfires wikimediafoundation.org/news/2025/ 08... Patrick Gildersleve / @gildersleve.uk : A glimmer of hope - the judge issued a warning shot towards Ofcom and the govt on protecting Wikipedia's operation in the UK. Wikimedia have focused on this in their response. We expect to find out more on Wikipedia's categorisation and obligations later this summer. This will rumble on... Patrick Gildersleve / @gildersleve.uk : Troubling news as Wikimedia's claim against the OSA is dismissed. This opens the door for onerous new requirements such as ID verification and stricter content moderation. These measures run antithetical to Wikipedia's practical operation and core principles as the encyclopaedia anyone can edit. Timothy / @herooftim : “The British government says the law is designed to protect children and remove illegal content. Technology Secretary Peter Kyle has said those who wanted to overturn it were “on the side of predators”. — Ah yes. Wikipedia. Famously full of pornography and predators Chris Stokel-Walker / @stokel : Wikipedia losing its court case against the Online Safety Act is a blow for them, but the Wikimedia Foundation believes the fight isn't over (and piled pressure on Ofcom to categorise platforms correctly) www.reuters.com/sustainabili... Mastodon: Craig Grannell / @craiggrannell@mastodon.social : Then: UK govt loses mind — Now: Wikipedia loses legal challenge — Next: UK loses Wikipedia access? — This legislation is way, way beyond porn and stated scope. There is no good reason to age gate an encyclopaedia *at national level* under the guise of protecting children. … Juan / @reidrac@mastodon.gamedev.place : The judge suggested that “Ofcom may need to find a particularly flexible interpretation of the rules in question, or that the rules themselves may need amendment in Parliament”. — Sure. Because you are not going to provide an ID to verify your age to access/contribute to wikipedia's pages; and the wikipedia won't geo-block UK users. … Bruce Lawson / @brucelawson@social.vivaldi.net : “the High Court of Justice dismissed the Wikimedia Foundation's challenge to the UK's Online Safety Act (OSA) Categorisation Regulations. While the decision does not provide the immediate legal protections for Wikipedia that we hoped for, the Court's ruling emphasized the responsibility … Graham Smith / @cyberleagle@mastodon.social : Result of Wikimedia challenge to categorisation regulations. #OnlineSafetyAct https://wikimediafoundation.org/ ... X: @bigbrotherwatch : ⚠️The Online Safety Act forces tech companies to censor lawful content or pay severe fines “We're now in a ludicrous situation where all UK internet users only have access to a childproofed version of the web unless we're willing to undergo intrusive age verification processes” [image] @tipcornk : @ReutersUK I'm assuming the hidden replies I can't see here but are counted in the reply number above are being censored by the “UK Safety Act”, alongside a ton of news tweets and political content that I can only see when I use a VPN now. @ambersulfr : @ReutersUK It's an encyclopedia... No matter how much nonsense happens under the hood, there's no chance this comes across as defensible to your average person. @senatorshoshana : It's so amazing to me that UK regulators are complaining about basically malicious compliance with the Online Safety Act and over-blocking content, when the law tells companies they have to make sure kids don't see even cartoon violence. OF COUSE they're going to over-block! Preston Byrne / @prestonjbyrne : The Wikimedia Foundation is an American 501(c)(3) nonprofit with no presence in the United Kingdom. Its First Amendment right to, from US soil, impart and receive speech to and from the United Kingdom should not be infringed by British censors. Washington must step in.

Context & Ripple Effects
Wikimedia had already warned that the UK regime could endanger volunteer editors in its earlier legal challenge, following its long-standing refusal to collect more data from UK readers or contributors than necessary under the earlier bill.
The dismissal does not settle Wikipedia’s eventual categorisation or obligations: the court left room for fresh challenges and cautioned regulators and government against materially disrupting its operation.
First-order effects
- Wikimedia’s current challenge to the categorisation regulations fails, so Ofcom’s process can continue while Wikipedia’s UK status is determined.
- The foundation retains a route to challenge later decisions, preserving litigation risk around any obligations that would require identity or age checks or stricter moderation.
Second-order effects
- Ofcom and the government face pressure to apply or revise the rules in a way that does not significantly impair Wikipedia, rather than treating a volunteer-edited reference service like a conventional social platform.
- The case sharpens the practical limits of identity-based controls: recent evidence of users bypassing UK checks with VPNs and synthetic IDs makes compliance burdens and effectiveness separate questions.
Third-order effects
- If the framework is applied broadly, online-safety regulation may increasingly hinge on service-specific classification and court review, not a single uniform compliance model.
- The broader policy tension is whether access-control rules can protect users without forcing data-minimising, public-interest services to redesign participation around identity verification.
The trend: This is part of a wider shift toward access-control regulation being tested against the operating models of open, volunteer-run internet services.
