Nostr is not perfect, I think everyone would acknowledge that, but many of the criticisms I've seen of this interview* center on the implied stance that a decentralized protocol (I still think of Pied Piper) removes liability. Which misses the point:- people can chose to develop applications or front ends to Nostr with any level of censorship they want. The point is the protocol is censorship resistant and open - not the front end(s).

There is zero reason that someone couldn't create a Twitter clone complete with private key management on a corporate server that exactly behaves like Twitter - complete with removing peoples ability to post by not letting them use their private key. Defeats the objective for many users but technically feasible and cheaper than setting up a new social media platform from scratch.

It's an oversimplification but think of http (Nostr) versus a website (front ends for users). Criticizing the open nature of Nostr is like implying the very open Internet standards were anti-business.
