Some one have to pay the ISP for the service they are providing. Suppose that Facebook is providing access to all websites in free basics. Where is the business model in that. How can Facebook profit from that? May be what Facebook is saying is right: “We are not against net neutrality”, but there is no way on earth that they could provide such service for free.<p>What are they suppose to do? Give people free access to whole web assuming that out of their good heart they will use Facebook? 
Note: I am not supporting Facebook.
