Depending on whom you ask, Facebook is either the savior or destroyer of journalism in our time. An estimated 600 million people see a news story on Facebook every week, and the social network's founder Mark Zuckerberg has been transparent about his goal to monopolize digital news distribution. "When news is as fast as everything else on Facebook, people will naturally read a lot more news," he said in a Q&A last year, adding that he wants Facebook Instant Articles to be the "primary news experience people have."

Facebook's stranglehold over the traffic pipe has pushed digital publishers into an uneasy alliance with the $350 billion behemoth, and the news business has been caught up in a jittery debate about what, precisely, the company's intentions are. Will it swallow the business whole, or does it really just want publishers to put neat things in users' news feeds?
