I'm not interested in educating you of all the constraints that each display ad tech company has to operate with. Suffice to say - no one is calculating or storing a list of "perfect ads" for you, nor does anyone particularly care that you like tentacle porn. You're really not that valuable.

Yes. Privacy freaks are overreacting on how deep ad tech cares to know about you. It's way less than what NSA or spying agencies(hello Facebook) are able to collect and use.
