I will take this question with me this weekend. What is the underdo thing of Nostr? https://overcast.fm/+JptiW-K9g
Maybe the whole "don't turn the user into the product" is an underdo? I guess it depends on the perspective on what is a feature.
Clients could still do that, but Nostr the protocol provides the freedom of choice to ditch those type of clients I would to ditch the word user, I remember a quote that only drugs have users. 🫣
Meh, I still like user, they are using the product, tool, protocol, whatever. But I see what you mean. What do you say instead of user?
