Mozilla warned UK regulators that age-gating virtual private networks would undermine privacy tools without addressing harms targeted by the Online Safety Act. The submission to the Department for Science, Innovation and Technology cites VPNs' role in concealing IP addresses to limit tracking and profiling. It argues that such restrictions conflict with equipping young users with security practices. Mozilla recommends focusing instead on platform accountability, parental controls, and digital literacy programs. Comparable measures appear in Australia's 2023 eSafety guidance and the EU's 2024 DSA enforcement reports, both of which document attempts to limit anonymizing services. Primary records show these efforts have produced limited age-verification compliance while increasing reliance on circumvention tools.
