If internet.org was really about providing internet access to people who otherwise can't access it, what is stopping Facebook from making it open? In current form lets say internet.org allows access to 100+ websites. I assume speed will be slow anyways. So make it open. Speed and data cap will be a deterrent for people wanting to abuse the platform (and things like torrent etc can be blocked anyways)
But I guess that will not serve facebook's interests. As an Indian, I actually prefer no internet at all compared to a moderated list that I am allowed to access. The way things are moving - Govt. has to act to provide internet in India for the last mile consumers anyways. With curated access there is a danger of wanting to maintain status quo because that kind of access - checks a tickbox.
