Nostr is nice, but total decentralization isn’t user friendly.
Federation allows some centralization, and that’s crucial, not only for UX but also scalability and more.
Big instances are not ideal, but are better than a near empty ecosystem.
Why is Threads adopting ActivityPub and not Nostr? 😉

On the Fediverse the admins have too much power to censor by banning users or defederating instances that don't ban them.
Nostr at least has not this disadvantage.
Mastodon could alleviate it by letting users revoke blocks for themselves:
