So I wanted to share this here for info and possible discussion.

Summary from Writer

Enterprising Angolans have used two free services—Facebook Free Basics and Wikipedia Zero—to share pirated movies, music, television shows, anime, and games on Wikipedia. And no one knows what to do about it.

Because the data is completely free, Angolans are hiding large files in Wikipedia articles on the Portuguese Wikipedia site (Angola is a former Portuguese colony)—sometimes concealing movies in JPEG or PDF files. They’re then using a Facebook group to direct people to those files, creating a robust, completely free file sharing network. A description for a Facebook group with 2,700 members reads: “created with the objective of sharing music, movies, pictures, and ANIMES via Wikimedia.” I was not admitted into the Facebook group and none of its administrators responded to my messages for an interview.
