Hi, I know Google Analytics very well, only the _ga cookie is used to recognize a web browser across visits.
If this is the right place to discuss this change, I'm surprised there is so few people participating regarding the impact of such a change on the internet ad ecosystem. You don't take the point about how ITP has been circumvented so far by the large ad networks. Google Ads, Facebook Ads and Bings Ads have deployed huge human ressources, have updated their ad delivery and tracking systems to be in a situation where they keep tracking ad conversion but some have lost capabilities in remarketing / targeting the proper audience. Give 3 names in the smaller ad networks that have done similar changes to adapt their technologies and platforms ! Even Criteo didn't update its tracking. Here is an article in French that explores that point with more facts https://www.journaldunet.com/ebusiness/publicite/1422902-apple-est-il-en-train-de-tuer-la-pub-web-sur-mobile/ Of course today there are abusive usage of cookies, cross domain cookie tracking, cookie sync operations, obscur third party data sharing with partners who are not identified, that don't get user consent, nor advertiser consent. I don't see a chance of stopping these without: - better legal rules where ad networks are responsible, not just advertisers or inventory providers - a common standard implemented in every modern web browser that allows to control which data is exposed to which tag / resource The patch you propose sounds to me like a try and error change. But it forgets completely to study the impact on user experience and on the ad ecosystem. I'm not a fan of advertising, but it fuels lots of money into internet content, services and technologies. Without ads, many sides of internet as we know it will collapse and disappear. Better governance is needed. Experiments without clear problem statement and solution design can be disastrous.
