We're willing to play the cat and mouse game indefinitely, if that's what it takes. Widely deployed trackers are limited in how fast they can try new tricks. And in practice, we know that ITP is working pretty well to block cross-site tracking: https://daringfireball.net/linked/2019/12/09/the-information-ad-tracking https://daringfireball.net/linked/2019/12/09/the-information...
- saagarjha 7y ago> Widely deployed trackers are limited in how fast they can try new tricks. How so? Tracking scripts are often included by a script tag that points at a website. Can’t the code be updated, “deployed” to websites immediately, and take advantage of the relatively slower release cycle of Safari?
- om2 7y agoMaybe I should have said that some tricks are slow to deploy. Sometimes the publisher only embeds an image form the tracker (the famed "tracking pixel"). Getting lots of sites to change that to script is a pain. Sometimes they need to deploy new server-side tech for a workaround. For the recent CNAME cloaking trick, they have to get sites to modify their DNS and change what URL they embed script from.
