Apple 2023 Analysis
Title: WebKit Standards Positions - The Topics API
Authors: Anne van Kesteren (Apple)
Abstract/Summary: Our analysis of the proposal assumes full per-top-level-site partitioning and no high entropy device fingerprinting such as IP address available cross-site. It’s important that any pre-existing privacy deficiencies on the web not be used as excuses for privacy deficiencies in new specs and proposals.
We do not think Topics API is a good addition to the web platform.
