Facebook has done some controversial things in its time, but Internet.org may be one of the most widely-debated. The app and mobile website are supposed to bring free Internet access to more than four billion people, which sounds good on paper, but Internet.org has been criticized numerous times for violating net neutrality by only offering free access to certain services and websites, such as Facebook’s own products. The initiative has since expanded to include eligible third-party apps and websites in order to address some of these concerns, and in order to better distinguish between the initiative and the Internet.org app and mobile website, Facebook has renamed them to Free Basics.
