For some reason Parker thinks nostr isn't censorship resistant because it doesn't have PoW. He probably doesn't know there is a PoW NIP. He also probably hasn't considered that nostr's tight integration with lightning can act as a form of PoW (imposing economic costs on certain actions.) 

 PoW can cost as little as a single sat 

 Parker needs to sit down like the tiny acorn he is or he will get a cost cut
