The loss of the early web due to web hosters not maintaining their own hosting and moving to walled gardens is painful and tragic, but it is not in any way similar (or functionally equivalent) to this blatant censorship.
But for the Western internet, it disappears because the people hosting those websites gave up, so all we have is archive.org. With this case, there appears to be a government-level purge.
