"The administrator of the Exploding Heads (EH) instance of Lemmy recently announced that at the end of August, EH would be leaving Lemmy and the Fediverse and moving to the Nostr network. He gave the increasing culture of censorship on the Fediverse as his reason for leaving. In fact, EH may not have been the first to leave the Fediverse in response to the 'defederation' it experienced. Rumors suggest that Gab gave up on the Fediverse years ago for this very reason, and that appears to be the beginning of the end of the rosy view held by some that the Fediverse would be an oasis of free speech on the Internet."
