Free Speech according to the idea of mostly left-wing oriented operators of Mastodon instances means to permanently exclude at least 500 instances worldwide from the federation because of "wrong opinions".
It took me more than a week of intensive research to find the part of Fediverse that was locked out by the Federation.
Mastodon, contrary to all praise, is degenerating into an even more censored platform than Twitter and Facebook combined.
