On the topic of censorship / cancellation my limited experience so far has shown me that defederation happens and plenty of servers are entirely unreachable from the rest of the ecosystem. I’m not sure if this is an argument in favor or against anything, but at least it shows me that there are different standards and ideas at play and they really don’t fit well together into a coherent view of what Mastodon is. It really depends on “which mastodon”. poa.st and hachyderm.io are both Mastodon instances but they generally don’t cross as an example.
It stands to reason that, in a cultural & political environment that encourages bubbles, fediverse would evolve into a bunch of several such bubbles - federating within each other, but not outside. Eventually, I hope we'll see some "frontier" servers that could be federated by different sides to serve as a meeting place for the brave souls.
