67 human rights, technology, and other groups have written to Mark Zuckerberg regarding Facebook’s suspect plans with their Internet.org initiative:
It is our belief that Facebook is improperly defining net neutrality in public statements and building a walled garden in which the world’s poorest people will only be able to access a limited set of insecure websites and services. Further, we are deeply concerned that Internet.org has been misleadingly marketed as providing access to the full Internet, when in fact it only provides access to a limited number of Internet-connected services that are approved by Facebook and local ISPs. In its present conception, Internet.org thereby violates the principles of net neutrality, threatening freedom of expression, equality of opportunity, security, privacy and innovation.
This comes from a very similar train of thought as the concerns previously raised by Mahesh Murthy.
