Did Facebook tilt the news?
Top-line: I think it's pretty unlikely.
But whether they did or didn't, though, it points to how unwise it is to trust one big company with the flow of news. And there's no reason to. It's not very hard or expensive to set up alternative systems. News people seem to assume that Facebook has it locked up, but I don't think they do. They may act like they do, it's a smart competitive posture. But tech is cyclic, and layered. To think that Facebook represents the best tech for all time for distribution of news, well they're not even the best tech now!
Imagine if a sports team gave up at the beginning of a season. It wouldn't make sense. This is a competition. There will be many ways of getting the news through computer networks. I'd bet good money on that. History is most definitely on my side.
