iOS 26.4 mandates UK age verification

This move sets a chilling precedent for OS-level geofencing and identity-linked device access that exceeds local legal requirements. Default-on AI content filtering turns the "open internet" into a walled garden that requires private data to escape, while mandatory verification using only specific IDs risks digital exclusion for low-income and vulnerable populations. Tying security patches to identity checks forces users to choose between device integrity and personal privacy, establishing a framework for future platform-level censorship based on nationality or government policy.
