I figured that we were overdue for a hot button topic. Cue the political discussion.
My hot take is that no, social networks should not be responsible for misinformation on their platforms. I believe in freedom of speech, and I believe in free press, and I also believe that as long as a social network makes it transparent that the content being published is user-generated content that belongs to specific members of their platform, then the social network is not acting itself as a publisher, per se, as much as it is a platform for end-users to self-publish.
