It's a bit sad many champions of democracy are realizing they can't handle real dissent. They seem more comfortable with control, limits and useless debates on media structures and platforms they can influence and control than the kind of actual dissent provided by Assange, Snowden and the wider platform of the Internet that allows people to freely exchange ideas.
Let's take it to the extreme, if citizens elect an flat earther or an extremist running on hate then its not a problem with democracy but a reflection of deeper problems with your society and education system.
Misinformation, propaganda, fake news are as old as human society and used by all countries and special interests, and can be addressed well outside the fundamental structures of democracy, free speech, dissent and free press.
