AdChoices is a program by the Digital Advertising Alliance (DAA), a consortium of digital advertising groups. Among other things, it provides what it calls a one-stop portal where people can ask more than 100 ad tech companies to opt them out of being targeted with personalized ads based on their personal data.
AdChoices’ offer was tempting. Just a few clicks on a single website and, like magic, I would stop all the ads I encountered from knowing everything about me? If only it had turned out to be so easy.
