The main reason I use an ad blocker is the amount of data the ads use up. Internet usage in Canada is sold by amount of data used, and Lord help you if you go over your data cap. I subscribe to a couple of major newspapers and they STILL ask to be white-listed. How fair is that? It is mainly the “video-like” ads, such as the one running on this page right now, that use up data. Print ads would be more tolerable.
