Even Criteo's workaround has been zapped...
Criteo’s Shares Plummet on Revenue Forecast
Apple’s stronger move against ad tracking will hurt, company says
"Marketers and advertising technology companies, including Criteo, use cookies to target and measure their web ads."
"Criteo had been utilizing a workaround to Apple’s feature called Intelligent Tracking Prevention, which rolled out on the Safari internet browser on Sept. 19."
"On Thursday, Criteo said iOS 11.2, the new version of Apple’s mobile operating system rolled out earlier this month, disables the solution it had been using to mitigate the effect of the tracker prevention function."
"Criteo said if it cannot build an alternative solution, Apple’s tracking prevention could affect its 2018 revenue, minus traffic acquisition costs, by 22%. Criteo is particularly affected because it specializes in an advertising method called “retargeting, which involves serving ads to people who have already visited a website to remind them to return. The method relies heavily on tracking users as they browse from site to site."
