This is the Facebook playbook: you lure in publishers by promising them a traffic funnel ("post excerpts and links and we'll show them to people, including people who never asked to see them"), and then the rug-pull: "Post everything here, don't link to your own site. Become a commodity supplier to our platform. Abandon all your own ways of making money. Become entirely subject to the whims of our recommendation system."
