Hi Ehsan, Thanks for the follow up. I don't have access to a macOS computer with that 12.0.3 version of Safari
On the other hand I have access to Google Analytics data for multiple sites, not the top 100 Alexa, but I don't see any evidence of a shift introduced by Safari 12.0.3 , for example through an increase in the share of new visitors with that version See that example https://photos.app.goo.gl/FTJoDLsYiJ17SPY46 The Mozilla organization probably has access to similar data. Instrumentation could also be a good option to assess the impact of such type of change. What I don't get is what is the assessment process in place to understand how such a change will be circumvented. Because it will. As many of the previous changes put in place by Safari ITP initiative. And the impact on the digital advertising ecosystem. The biggest ad networks might suffer. But will provide solutions, estimates, alternatives... And most of the smaller networks, with less agility, less money and resources, less skills, may break, get sold to the biggest, may close. Is the goal of this change really to enforce the role of the largest ad networks ? Why not. They tend to honor laws more likely than others... 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 ? _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
