I'm not sure how Pleroma (written in Elixir) could be a fork of Mastodon (written in Ruby). Both Pleroma and Mastodon implement ActivityPub, but that alone doesn't make either one a fork. Truth Social does use Mastodon's code with the federation features stripped out like Gab, but what I meant was that I couldn't find any reports of Truth Social claiming to have evidence of hard-coded political censorship in Mastodon (other than the generic blocking features found in most social networks).
