WebKit says it will block identity-resolution tracking infrastructure
WebKit says it is moving to block identity-resolution infrastructure that collects email addresses through logins or sign-ups, links them to persistent tracking IDs and uses them for profiling or ad targeting. The post frames the change as an extension of Apple’s existing anti-tracking protections.
Why it matters: Marketers, ad-tech providers and measurement teams may need to reassess identity-based targeting, attribution and audience strategies in Safari/WebKit environments. The consequences are likely durable because the change extends an established browser-level shift away from third-party tracking rather than representing a temporary product update.
