Who pays money to show ads on shared.com? At first glance it looks like generic adsense, probably opted in to any available ad exchanges. So presumably facebo

Who pays money to show ads on shared.com? At first glance it looks like generic adsense, probably opted in to any available ad exchanges. So presumably facebook is miffed that it pays better to take eyeballs away from their feed and point them at google ads. It does make one wonder why FB doesn't stick adsense on the feed or increase the price of their ads; clearly there's plenty of room for arbitrage.
