FB to this date still owns the internet.org domain, which was literally their marketing at the time. Free plans from mobile carriers had/have access to a few selected websites and not the rest of the real internet.
While I agree that the courts decided against this at some point, it was around 13+ years too late, because a generation of mobile users got hooked already.
Meta even went as far as deleting their internet.org website from the web archive, all years result in a 404 now. Interesting.
