How does this help?
The article cites the problem of a host web page telling the ad server who is viewing the page. This then allows the ad server to link the user to the ad it’s slinging.
But this problem still exists with Googlies “solution”; the host ad can just tell the ad server the IP address of the client and so the ad server will still be able to associate the ad with the page and vise versa. Just an IP address is not a perfect identifier but it will work most the time.
Of course none of the above addresses Googlies’ next attempt to abuse its users
