Almost this whole issue boils down to this, "do we need, and if, how do we handle forced content removal". And I have to say I'm on the freedom side here. Just like with encryption, you can't have a "trusted" middle men with a backdoor. You can't trust a state, a corporation, a "committee of wise men". You can't have a central dependable authoriser for a complex, abstract entity like content.
There are two forces at play here, general public ("everyone else outside the poster") and law enforcement.
- Groups will always be able to flag/hide/shadowban content. Yes this is not not scaleable to millions of people/posts (without masses of slave wage moderators or automation, both which would make ample mistakes). But I also think that communities are not scaleable to millions of people/posts. For all the necessary "common space", it is, and probably should be "the frontier/wild west". Clients might be restricted from accessing it or may have filtering safeguards.
- Law enforcement should have the right to pursue people posting illegal content in real life, and remove it on their behalf with whatever means they have at hand - no matter if in the US, Europe, China or North Korea. But they should be only able to do this via their own (black-hat) methods and not built-in switches served conveniently by the network protocol. Just because the digital world allows complete control, that doesn't mean society should utilise it for its own steering.
In the end my guess is that such debates are kind of needless/theoretical - the world will gravitate to some similar kind of self-balancing anyway, like how it did with digital content piracy.
