Maybe it's a myth, but if so, it's an influential myth. I first heard this story about 10 years ago when I was new to the business and working on ad tech. It was used as an example of "what not to do" (because creeping out customers is bad for business.) The ideal, I was told, was to toe the line as close as possible. Creep on customers, but don't let them realize it. Hide highly targeted suggestions among less accurate suggestions, to disguise the efficacy of the tracking.
