Decline All Button: Not a Solution

Executive Signal Summary

The piece argues that implementing a German TTDSG-mandated 'Decline All' button in cookie banners may not resolve cookie-consent complexity and could degrade user experience by forcing re-entry of information during shopping. It cites France as a reference, where CNIL’s 2020 cookie guidelines require a symmetrical first-layer design with both Accept and Decline options and offer alternatives like 'Continuer Sans Accepter'. Didomi’s platform analysis in 2021 shows consent rates falling after CNIL changes: overall consent dropped from 94% in February to 86% in April, while 'Continuer Sans Accepter' dropped from 87% in April to 73% by October. France Médias Monde notes the Decline All feature did not harm business results. The article also highlights ongoing regulatory developments (Google Chrome restrictions, ePrivacy, Digital Services and Digital Markets Acts) and argues that skilled facilitators are essential for effective consent management.
