I am a bad person to ask because I am pro-nostr and am therefore unlikely to understand his criticisms properly. My impression of his opinion, which is probably tinted with my nostr-colored glasses, is that he has two main criticisms:

- nostr's design and usage patterns discourage key rotation/recovery
- nostr has no good methods for creating/storing non-public content 

 And what do you think about this DWN thing? I’m not sure I understood it 

 I haven't read the docs yet so my only impressions are these:

- csuwildcat is knowledgeable/credible on the topic of decentralization
- he says dwn relays are better than nostr relays for most purposes
- I want to check it out to see if I agree but I am busy right now
