Comment The fine line between author and carrier (Score 1) 221
I think the discussion about "common carrier" elsewhere in the comments misses the point. Social media platforms do not wish to be merely common carriers because a common carrier only transports messages by others and what they want to do is both monitor and control which messages reach specific users because they make money selling information about their users and delivering targeted advertising.
It is the secret, proprietary algorithms of Google, Twitter, facebook, et al. which are the problem here. The social media platforms are not merely common carrier if they are actively pushing certain messages whether for financial gain or ideological purposes. At a certain point we might consider them the author of the content they decide (or calculate) to push. We cannot know if the murderers in this case were fed hateful "instructions" by a YouTube algorithm or not but if they were then that is a problem that should be addressed, certainly.
