I don’t really care if a Nostr client is a custodial as long as they explain in a FAQ that someone won’t be able to export their Npub and use another client.

Some people don’t care and like the convenience.

It’s a free market isn’t it? Why would freedom only equate self-custody? People can do whatever they feel like and are comfortable with as long as they have all the only layered out in from of them.
