In April 2015, Mark Zuckerberg visited India to help promote his nonprofit Internet.org's efforts to provide Internet access to the billions of people around the world (two thirds of the world's popoulation) who still lack Internet access.  The nonprofit provides a smartphone app with free Internet access that is limited to several programs, including Facebook (minus the ads): "The Internet.org app provides free basic services in markets where internet access may be less affordable. It allows people to browse selected health, employment and local information websites without data charges. The app is currently available in parts of Africa, Latin America and Asia, and will continue to expand to more countries around the world." 

While noble in its intentions, the Internet.org service is possibly in tension with the principle of net neutrality because the Internet.org service may be seen as discriminating among applications that people can access.  Until Zuckerberg's trip to India, the potential conflict with net neutrality sort of flew under the radar.  But the Times of India and other publishers refused to join the Internet.org platform and encouraged others to do the same based on Internet.org's potential conflict with net neutrality, a principle that does not allow access providers to privilege certain content over others.  One controversy is whether "zero rating" (in which Internet websites negotiate deals with telecom companies to not count uses of their sites to their subscribers' monthly data plans) violates net neutrality.  

On April 17, in a Facebook post, Zuckerberg vigorously defended Internet.org's service and said it didn't conflict with net neutrality.  But on May 4, in a video posted on Facebook (see below) Zuckerberg offered a concession to his critics and announced that Internet.org would allow any developer to qualify for the free Internet service that Internet.org provides if the app satisfies certain guidelines.
