When the company that makes most of their money from advertising starts policing other people’s ads, one can very quickly figure out that there might be some conflict of interest going on.
I personally believe that the majority of Google’s employees sincerely want to improve the quality of the online experience and block bad ads. Despite that, history has shown that when a company becomes a monopoly they tend to focus on protecting the monopoly rather than improving their customers’ experience.
By having both the largest ad network in the world and the most popular browser in the world Google is definitely the largest and most important online ad player.
It may be time to acknowledge this fact and look into regulating the online industry the same way we regulate mobile carriers or broadband companies and protect consumer interest.
