An "internet" service run by Facebook is going to be fairly self-centered anyway you look at it.
Fun fact: with normal internet access, when you access an HTTPS-encrypted website, your ISP won't be able to know what that encrypted content is (in theory). However, internet.org traffic is decrypted by Facebook, and then re-encrypted before the users receive it, presumably to make sure the data can't be intercepted by any governments what might want to stifle free speech. Facebook claims they're not storing said data, that they value the internet.org users' privacy. I think we all know how unlikely that claim is. Given Facebook's behavior, and the fact that they automatically decrypt and re-encrypt people's communications (as opposed to relaying said communications without decrypting them), it seems unlikely that Facebook isn't spying on users.
Anyway, as for copyright infringement (or "piracy", as they call it), I don't know if this is illegal in either of the aforementioned nations. Any corporation who tries to force American copyright laws on these nations deserves to be put out of business. If these people can't afford real internet, they probably can't afford the music, movies, etc. they are illegally downloading anyway. So, the music and movie industries aren't loosing anything here.
