The public doesn't trust politicians, the government, or its official experts. Facebook is a public forum, and the public uses it to express their mistrust. Politicians then pretend that Facebook is the reason no one trusts them, because shooting the messenger is easier than admitting that they don't have much authority any more.

Are there major problems with Facebook? Absolutely. But the motivation behind attacks like the one leveled by this journalist is transparently to deflect blame off our incompetent political establishment and onto an easy scapegoat. The truth is that if politicians want people to trust them, they're going to have to figure out how to convince those people. Making Facebook or Twitter delete your enemies' posts hasn't worked in the past and it won't work in the future. This is a free society. You don't get to replace the public's opinions just because you declared those opinions "misinformation." Maybe in China, but it just doesn't work that way here.
