It's extremely clear that Facebook is setting itself up for an anti-trust action in the next few years. Their very aggressive leveraging of their near-monopoly in social to try to kill Snapchat, will be viewed in hindsight similar to Microsoft attacking Netscape with its OS position. If Facebook succeeds, it'll leave them with an overwhelming monopoly in social, there's no scenario under which they won't be pursued by the government thereafter. Plus, you can bet Snapchat and its investors will begin to howl loudly the harder Facebook presses.

Zuckerberg's lust for market domination, will unravel or stagnate his kingdom if he's not very careful. His behavior at this point is looking ever more Gates-like when it comes to trying to knock-off the competition while possessing a near-monopoly (you can do one or the other, but if you're a $400b company and you try to both kill all your competition while having such a position, good luck).
