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.

I say there is no financial compensation for users, but many users feel themselves amply compensated by the aforementioned provisions: ease of use, connection with others, and so on. But such users should realize that everything they find desirable and beneficial about those sites could disappear tomorrow and leave them with absolutely no recourse, no one to whom to protest, no claim that they could make to anyone.

This is of course a choice you are free to make. The problem comes when, by living in conditions of such dependence, you forget that there’s any other way to live—and therefore cannot teach another way to those who come after you. Your present-day social-media ecology eclipses the future social-media ecology of others. What if they don’t want their social lives to be bought and sold? What if they don’t want to live on the bounty of the factory owners of Silicon Valley? It would be good if we bequeathed to them another option, the possibility of living outside the walls the factory owners have built—whether for our safety or to imprison us, who can say? The open Web happens outside those walls.
