I think you really have to understand Zuckerberg's "origin story" to understand why he is doing this. He created a thing called Facebook that was wildly successful. Built it with his own two hands. We all know this. But what is less understood is that from his point of view, Facebook went through a near death experience when mobile happened. Apple and Google nearly "stole" it from him by putting strict controls around the next platform that happened, mobile. He lives every day even still knowing Apple or Google could simply turn off his apps and the whole dream would come to an end. So what do you do in that situation? You swear - never again. When the next revolution happens, I'm going to be there, owning it from the ground up myself. But more than that, he wants to fundamentally shift the world back to the premise that made him successful in the first place - open platforms. He thinks that when everyone is competing on a level playing field he'll win. He thinks he is at least as smart and as good as everyone else. The biggest threat to him is not that someone else is better, it's that the playing field is made arbitrarily uneven. Of course, this is all either conjecture or pieced together from scraps of observations over time. But it is very consistent over many decisions and interactions he has made over many years and many different domains.
