I'm not sure if I described it clearly, with this mode on, all of your traffic was being redirected to a Shaw server before being routed to where it was supposed to go. It was like being connected to a vpn that existed solely to serve me ads. They were blocking ads on websites and replacing them with their own from their servers, I would get popup ads from them that were not being stopped by adblock, every misspelled or dead URL would take me to their landing page full of ads for their services. Not only were they interfering with my traffic, but they were interfering with the monetization of website. As much as I dislike ads, I'd rather the site owners get the ad revenue for my browsing than a company I'm already paying for internet.
