BiglyBadgers, I agree with every word of your last two posts.
Which I appreciate isn't very constructive, as I'm basically joining you in going, "Hmm, hard."
A while back Facebook were, IIRC, denying they were a "news organization" - while providing a newsfeed onto people's pages. They've now begun to contemplate the fact that they are, in fact a news organization, and that there might be a reason old-fashioned news organizations (most also private companies) have codes of ethics.
There's a major change from the previous structure. It used to be that news organizations broadcast, and readers/watchers discussed it in the pub.
Now readers/watchers bring their discussion back onto the comments page of the online paper, onto their "personal space" at Facebook, or onto a social network like MN. Instead of carrying out their free speech in the pub, everyone's publishing, and using other people's platforms to do so, in a way they couldn't previously do (they could write a letter to the editor, who'd decline to publish on "grounds of space"...).
So the landscape in which we exercise free speech is completely different from 20 years ago. We haven't yet caught up with new maps.
