Yes. The problem is most of these companies that want to fight "fake news" would probably almost completely focus on "new sites" that have fake news, and perhaps a couple of other "more obvious" big sites like Breitbart. But what happens when the fake news comes from CNN? Will Facebook block CNN or WSJ articles that spout lies and are blatantly incorrect? The problem with this is that these days, you often also get the "real news" from smaller sites, like DemocracyNow, or others even smaller, that report on NoDAPL protests when none of the big news sites do. What if Facebook gets used to censoring these sites, though, even though they report the real news out there? And would we even know? After all, they are small sites, that few people would know about in the beginning.
