Facebook founder Mark Zuckerberg today said his company is committed to net neutrality but supported zero-rating plans which have been criticised by many as violative of the principles of free Internet. Interacting with students at Townhall in IIT Delhi, Mr Zuckerberg said, the world's largest social network Facebook is working both in terms of supporting regulations around that principle and building an open platform for developers. <br/><br/>He said, Internet.org and Facebook are 100 per cent supportive of net neutrality and he lobbied for it across the world. Mr Zuckerberg said providing free Internet to everyone in the world is expensive and telecom operators spend billions of dollors each year bringing Internet to users. On zero-rating plans of telecom firms like Bharti Airtel, Mr Zuckerberg said that those who are against zero-rating should look at student who wants free access to Internet for their studies.<br/><br/>AIR Correspondent reports that Net neutrality stands for equal treatment of data by service providers without any discrimination and prioritization of one type of data over the other. The neutrality debate flared up in India after telecom operator Airtel had launched a platform, Airtel Zero, that would have allowed free access to some websites on its network. Following criticism by political parties, government has been consistently maintaining that it is in favour of Net Neutrality.
