Ben Thompson:

There are even more fundamental problems, though: how do you decide what is fake and what isn’t? Where is the line? And, perhaps most critically, who decides? To argue that the existence of some number of fake news items amongst an ocean of other content ought to result in active editing of Facebook content is not simply a logistical nightmare but, at least when it comes to the potential of bad outcomes, far more fraught than it appears.

This is the biggest concern I have with this fake new debate: who decides what is and isn’t fake and could that position be abused?
