I guess you could argue Facebook should be shutdown as parlor was. Although parlor was only used for hate, Facebook didn't do anything to stop it either. I think a big issue is how facebooks algo (and others) are built for maximum profit which at the same time also radicalizes people in their filter bubble.
I think Facebook should be broken up but I havent heard any good ideas yet regarding how to somehow regulate social networks. Beyond hate speech, I dont see any reason to limit what people can say. Somehow limiting how the network connects people, or how content propagates, seems like the key. Only FB has done the social experiments at scale to know how to engineer this, which is faintly ironic.
Clearly, there is flipside. Private Facebook groups to share hate speech or otherwise echo awful thoughts. Legions of bots controlled by political organizations or nation-states trying to divide and conquer a population. It is a losing battle to moderate these platforms.
Facebook has no inherent right to exist as it does, or rather, make a profit as it does - and I wonder if extreme measures, such as a partial repeal of section 230, should be considered. Like all laws, small-p-progressive measures should be taken. Small and medium websites should not necessarily be held liable for content posted by others. But as a network grows to have hundreds of millions of users, perhaps they should?
I'm not sure either.
