I’m not fully convinced that’s traditionally true. For me it’s just about the purposeful hostility, that a small client who wants to respect their users preferred_name or maybe better mention_name just can’t possible offer that. They can agree with a specific client dev, but at the expensive of disagreeing with others. The best I’ve seen is astral ninja, which would truncate if they are all set to the same, including the nostr address. That however looks super redundant on a client like damus.
