If I can address that in 45 seconds, I would say it isn't necessarily freedom of expression that is at issue.
To regulate that, we have to ask some questions about freedom of expression. For example, if obviously fake news is used for parody or satire, we can discuss imposing limits on that. For someone who produces or uses that kind of content, it is not necessarily their right to freedom of expression that is at issue, in my opinion. There are other rights, individual ones, in play.
