Wikipedia has lost a legal challenge against the UK's Online Safety Act, which could require the site to verify the identities of its users. The Wikimedia Foundation argued that the rules are too broad and could threaten the safety and privacy of its volunteer editors. The court rejected the challenge, but the judgment emphasized the responsibility of the UK government to protect Wikipedia. The foundation may still be able to challenge Ofcom's decision if the regulator classifies Wikipedia as a Category 1 service.
