I wonder if this will undo, in large parts, the "new" web that's being worked on for the better part of this millenium. Third-party cookies are blocked, presumably YouTube-like redirection to make cookies first-party are detected, other cookies are held no longer than a week, etc. So advertisers will turn to browser fingerprinting, so soon we'll see requesting window/viewport dimensions as being flagged as insecure. Even CSS media queries aren't safe as they can trivially be used for fingerprinting (and I have seen CSS where max-width was beeing queried in steps of 3 pixels out of sheer incompetence). Also caching/timing "attacks" for fingerprinting. And finally, arbitrary JavaScript execution will be questioned, as it should've been a long time ago. It'll be interesting to see this arms race enroll, with Apple protecting their users (and also their apps and iDevice market) and Google protecting their version of freedom (and unchecked privacy invasion and monopolization of the ad space and web).
