I have some sympathy for your position, and I'm against the banning of Internet.org, but your reply is ineffective because it misses the arguments against the service.

Even something given with no ulterior motive can have destructive effects on the recipient society, since it eliminates potential competition, while often not providing a better good or service. How many future ISPs offering cheap open internet access will not even appear?

On the subject, though not directly about Facebook, I suggest this interview with the creator of Poverty, Inc.: http://www.econtalk.org/archives/2015/11/michael_matheso.htm...
