According to Sean Sullivan, F-Secure Security Advisor, the results show that online tracking has become a serious problem, and is costing people time and money. "Websites can typically justify some degree of online tracking to help them deliver better services to people, but this experiment shows that it's gotten way out of hand." said Sullivan. "The amount of tracking is increasing the amount of work browsers are doing and giving people a browsing experience like they, or maybe their parents, got in the 90's with dial-up Internet. It's basically becoming digital pollution that's eating up bandwidth, which justifies higher prices for data, which are then passed on to consumers."
