“It is common to refer to universally popular social media sites like Facebook, Instagram, Snapchat, and Pinterest as “walled gardens.” But they are not gardens; they are walled industrial sites, within which users, for no financial compensation, produce data which the owners of the factories sift and then sell. Some of these factories (Twitter, Tumblr, and more recently Instagram) have transparent walls, by which I mean that you need an account to post anything but can view what has been posted on the open Web; others (Facebook, Snapchat) keep their walls mostly or wholly opaque. But they all exercise the same disciplinary control over those who create or share content on their domain.”
