It's different because Facebook has captured nearly every American adult and they have a Google-like (in search) dominance over social. There's no news platform in US history that has ever come even remotely close to being able to claim that. They're just about worth more than every US media company combined, their reach and financial power are already incredible; four years from now they'll be as profitable as Google is today and their reach will likely have expanded further.

I can't see a scenario where Facebook manages to avoid anti-trust action against it in the next four to six years, both in Europe and the US.
