I appreciate trackers are "well-known", but only to a specific class of technical individuals. "Nontechnical users" is basically everyone. They have a right to be outraged, especially when a technology is understood asymmetrically well by the class of individuals who exploit this asymmetry to their advantage.

Both the individuals visiting these sites, and possibly even the people making the decision to implement tracking don't know their browsing data is being used for anything other than analytics by the website provider, (if at all by the user, who likely feels safe behind a private browser).
