Free speech has taken quite a beating in recent days. It's weird watching many of my friends and people I respect cheering while it happens. I honestly don't know what we do to fix our current situation where lies so easily go viral, but making Twitter arbiters of truth doesn't seem like the best solution.
Twitter is a community and all communities require some level of moderation. There's never a situation where you let people say whatever they want, whenever they want without any moderation at all and everything goes well. You have to set some of sort of standard. We already do this as a society, so why shouldn't that extend to Twitter?
I see many "it's just moderation" takes on what Twitter is doing, but what Twitter and other platforms are now doing goes beyond what most platforms have traditionally enforced in their moderation. Hiding user content that the platform unilaterally perceives to be untruthful is really a new milestone.
