Can you not see you’re suggesting segregation of the entire Internet?

What happens when registrars cut them off? No DNS routing for them until they build their own registrar? Will the point at which the segregated internet’s join become a DMZ guarded by both factions?

This entire app, and business, was shut down for a few bad actors. Traditionally you subpoena for info, but cancel culture stepped in again.

But that requires an ISP and DNS (which are also often censorious).

That technology is not secret, they are “free” to build their own. Like every other company that builds broadcast platforms, if they want to play, they’ve got to pay.

But Parler won't need to do this - there are plenty of hosts who aren't going to join in with the coordinated effort to silence the speech of those who aren't on the 'correct' side. Info Wars and OAN are still on the internet.

Surely, if they wanted to, they could buy cloud compute resources from a company based outside the US. Why must they be on Amazon just for access to its web services platform?

With net neutrality, they would not need to own an ISP. They might need to find a friendly place to host their servers though.

So Parlar can bifurcate and build their own ISP/DNS.
