Ads are only barely tolerable in the first place because they might deliver revenue to the owner of the site you're visiting. If the browser replaces real ads with its own, then it is no better than the scummy ISPs and WiFi access points that pull the same tricks. Also, have we not learned by now that the proper way to add to the web browser experience is through an extension? There's no reason to install an entirely new browser for one feature that is already covered by extensions in other browsers. Develop an extension and expect people to continue using the browsers that they have.
