PUBLISHERS OPPOSE W3C PLAN TO KILL THIRD-PARTY COOKIES

Summary from the TLDR Web Dev newsletter

The Movement for an Open Web (MOW), a web publishers' advocacy group, has filed a complaint with the UK's Competition and Markets Authority challenging the World Wide Web Consortium's (W3C) call to eliminate third-party cookies. MOW argues that the W3C's position is anti-competitive and favors Google over smaller publishers, who rely on third-party cookie data since they don't have access to the large first-party data sources available to tech giants like Google, Apple, and Meta. The complaint asks the CMA to pressure the W3C to withdraw its announcement supporting the removal of third-party cookies, claiming it violates antitrust obligations and Google's previous commitments to involve competitors in privacy-related design processes.
