The webkit engineer behind "Safari’s Intelligent Tracking Prevention" on Twitter confirmed when asked there have been no changes to how it blocks GA in the new version, it just is now visible in the report. And details, ITP doesn’t block loads, it blocks cookie access, deletes cookies and website data for sites you don’t interact with, downgrades referrers, and more. Its cookie blocking applies to all third parties." I responded that it seems all the new sites are reporting that GA is now being blocked/prevented in the new version are incorrect then. And these headlines appearing on Hacker News it looks like will only further unintentionally spread that misinformation.
