Earlier this year, the Federal Communications Commission voted in favor of stronger rules to keep Internet service providers from favoring some data traffic on the Internet over others. The February FCC decision was hailed as a victory by Net Neutrality advocates, or those who believe that the only free Internet is one where "all data is treated equally" by the companies that transmit it.
Critics argue that Mark Zuckerberg's Internet.org initiative isn't a charity, but rather a method of control. Zuckerberg can turn that around and prove his global connectivity project is truly good, but only by allowing the places he's connecting to eventually make his service irrelevant.
