Yes, it's sad. Mastodon will remain the media's darling as they remain predominantly positioned towards one spectrum of the political isle.
On Mastodon, I regularly see more, far leftist Ideology and propaganda than I even ever had on Twitter. Incredible echo chambers with the Fediverse.
And I consider myself a centrist. So, to experience what I'd consider "extreme" forms of Liberalism has been eye-opening.
In contrast, Nostr is a balance of mostly centrist, AnCaps and right wing. Little to no leftists and Marxists/Leninists here. Mix in the love of Bitcoin and it's easy to see why one side would be more critical and dismissive of Nostr than that of Mastodon as it already supports their subscribed world view.
