- those who struggle with freedom of expression on centralised systems.

There are no provisions for anonymity in Nostr, are there? The deterrent freedom of expression in countries like the US is the police knock down your door and drag you off to prison or gulag. I suppose if you use Tor to hide your IP, Nostr is ok for that. (Use pen name.)

Nostr can help those canceled on centralized systems by showing them that centralized social media is stupid. There have been many decentralized/federated social systems since before DNS (why would anyone use farcebook, etc?) But Nostr may be the first to provide a way to monetize content (the legit reason to use youtube/rumble).
