And, honestly, good-faith efforts to keep objectionable content off their networks that fail because of volume due to a one off thing like the terrorist attack in NZ aren't really the problem, the problem is what they choose to allow on their platforms because policing hate speech isn't an-cap enough for them and/or bigot ad revenue is just as good as anyone else's.
You asked what the consequences might be for Facebook et al if we expect them to behave like conventional publishers, but what about the consequences if they don't? This isn't the first mass killing where the perpetrator had links to hate groups allowed to fester in spaces provided by one of the major internet companies, eventually governments are going to take an interest and force them to do act - especially if the next incident is in the US and it's that or dealing with gun control. They'd better off doing it on their own terms than having it forced on them.
Also TFW Lewk makes better and more pertinent arguments than Hazir.
