Thanks for the comment John. Insightful and nuanced as always. I'll address your points in the order you left them in.
I don't think a country banning a social media network is the same as deplatforming someone from say Facebook or Twitter.
Especially since these networks are opaque in their usage of mining data. I'd say the prevailing opinion is that social media does more harm than good. That should give a country plenty reason to say 'hey, this is hurting our populace - let's get rid of it.'
This probably won't happen in a country like America, but if social media continues to undermine the first ammendment I just don't see how our country we'll last. Seriously.
So, in a country like America I hope the government breaks up the monopoly or at least tells social media to act in accordance with the first ammendment.That might sound draconian but it's either let the social media companies continue to run amok or place some sort of regulations on them.
I don't see social media as a weapon at all, since a weapon is neutral. It's cold and has no feelings. The same cannot be said about social media.
I think we can, 1) Uncensor the networks and let everything run down the pipes. 2) Let social media companies continue to do what they want and rule the digital economy 3) See if blockchain networks catch on and compete 4) Expect authoritarian centralized solutions like what's happening in China.
