Amazon aren't the only provider of hosting services, even if they are one of the largest. It's entirely doable to shift providers, even in the face of censorship - The Pirate Bay is one long-running example of this.

I'm not sure how you missed the point by that much. Infrastructure bans are a thing now. You can't produce an app to compete with Twitter and Facebook if you don't have access to scalable infrastructure. Moving to a different host to get canceled there isn't a solution.

Yes you can, it just means the scalability has to be designed in without using AWS/GCP/Azure services. Just like we all used to do it.

"Build your own country" would be a nice start to another civil war.

I would greatly appreciate if the Trumpists would go form their own nation.

I recognize that you were being facetious, but this is work a look.

Greater decentralization, smaller polities and a less powerful federal government could be a workable solution. It doesn't have to go to the point of secession. It is possible to respond with tolerance and let all sides live according to their wishes.
