See https://developers.google.com/analytics/devguides/collection/analyticsjs/cookie-usage#analyticsjs. Google Analytics relies on two user identifier cookies, one expiring in 24 hours and one expiring in 2 years. I'm not sure how the two identifiers are linked together but it seems that they already treat repeat visitors who come back to the site in less than 24 hours in a special way. That may explain why you haven't seen any impact as a result of this change. > What I don't get is what is the assessment process in place to understand > how such a change will be circumvented.

That is a strange proposition. If you have any concrete worries please do share and I will be happy to discuss. Vague concerns like this usually read like the fear of the unknown and are usually not helpful for having a productive discussion. > Is the goal of this change really to enforce the role of the largest ad > networks ?

The goal of this change is to ensure that third-party scripts, when running in the context of a top-level site, cannot abuse its cookie jar to store cookies that can uniquely identify visitors and can be used to keep a record of their browsing history across websites. This change achieves the goal by ensuring that such identifiers, once stored in the top-level site's cookie jar, will expire in one week maximum, and therefore the risk of the user being tracked by the companies that serve those third-party scripts will be restricted to that window of time. > Questioning anyway... > > This no just a technical decision about a web browser dropping an internet > standard. > > What do you think ? > What does the community thinks ? > If you have more feedback to share, this is the right place. I would recommend to keep the discussion focused on concrete technical issues please and avoid FUD ( https://en.wikipedia.org/wiki/Fear,_uncertainty,_and_doubt) through referencing claims such as dropping an internet standard or enforcing the role of certain companies. I would love to continue to have a discussion around the technical merits of this feature.
