That doesn't really make sense. Facebook is a large advertising platform for journalists and media that have existed for a very long time. It's not exactly a space for creators like Youtube.

That's outdated thinking; see my response to Mononokay. As much as a year ago, journalists might have seen it that way. What has changed, and why the tone has changed, is that almost no journalists today see Facebook as anything but a competitor. It doesn't even matter if they were right then or are right now, or both, or neither. That's just the zeitgeist.
