Also important to realize that social media is the main traffic acquisition point for most news websites. Imagine the economic pressures they are under if they lose that resource even for a short time. No mainstream media outlet can afford that.
Example: Imagine Ukraine blows up a bus filled with civilians (war is hell, right?). If your news organization reports on such an unpopular story, high chances are the untrained working-for-free facebook/reddit/social media moderator will flag you for propaganda and you will lose out on days of revenue. So you self censor on sensitive topics. Or perish.
Social media moderators are the new gatekeepers of information and that terrifies me.
