I would be more worried if I didn't have personal experience with digital marketers, and the businesses that hire them. They (ad tech) sell amazing, sometimes very scary, intrusive, tech but the implementation is almost always comically bad. The privacy concern is legitimate, but there are only a handful of brands smart/evil enough to use it as intended. The most common terrible example is Amazon ads: "No I don't want to buy another toilet because I JUST bought one". If Amazon can't figure this out, who is?
