A recurring complaint in most of the post is the inability to separate desktop users from mobile users. This makes it very difficult to optimize their advertising strategy. I find it hard to believe that Facebook is not capable of separating mobile (smartphones, wearables and tablets) and desktop traffic in a reliable fashion. I don't know if that's intentional, or why it takes so long to address this problem. But it's hard to deny that right now the only beneficiary of this foggy situation is Facebook.
