How Verizon and Turn defeat browser privacy protections

Verizon advertising partner Turn has been caught using Verizon Wireless’s UIDH tracking header to resurrect deleted tracking cookies and share them with dozens of major websites and ad networks, forming a vast web of non-consensual online tracking. Explosive research from Stanford security expert Jonathan Mayer shows that, as we warned in November, Verizon’s UIDH header is being used as an undeletable perma-cookie that makes it impossible for customers to meaningfully control their online privacy.

A virtually unchecked and unbound company with near-monopoly status in many US areas doing something scummy? I am so surprised.
