Is google using this in their own products? They were just fined $170M in the past few days!
If they cared about actual privacy, they would go after no-name ad networks and data mining companies.
As far as the companies they go after, I think going after large brand-name ad networks and data mining companies like Google is at least as important as going after the no-name ones.
(not selling per see, more like carelessly giving away)
