And the type of tracking they’re referring to is more like selling-your-data-to-third-parties tracking, not Google or New Relic or something. Maybe sales funnel tracking and interstitial popovers. Your average Adblock doesn’t distinguish between tracking methods and goals but trying to block all pages that load Google Analytics would probably lead to an incredibly small pool of websites, which would worsen the results.
Anti-tracking has gone mainstream enough among America’s elite that I’ve seen executives who are otherwise not tech savvy find themselves unable to load a page (or follow through a tracked link in an email), figure it’s because it’s infested and—on that basis—move on from that vendor.
