Imagine if YouTube and Facebook were government-funded public utilities that didn't rely on advertising revenue but otherwise functioned as they now do. What effect might this have on the radicalization problem that Zeynep Tufekci describes? A. With no economic incentive to keep people engaged for as long as possible, neither platform would have a reason to serve up radicalizing content. B. Without the lure of being fed a constant stream of emotionally charged content, people would gradually abandon both platforms. C. It would radicalize people even more because neither platform would be bound by advertising regulations. D. Few people would want to use government-run social media, so neither platform would contribute much to radicalization
