Facebook and Twitter must invest in the deal in one way or other. Facebook's free access in India and some other countries is part of their internet.org project (or the team that deals with that). In that model, Facebook has a partnership with the local telecoms. The telecom opens access to that domain for every customer and Facebook pays the telecom for the data access.
