Nostr isn't going to blow up because one small Bitcoin creator goes Nostr only, we already have ample proof of that. For the reasons I already laid out, crippling his reach and opportunity to make money doesn't seem like it makes sense.
I don't hold any ill will towards creators who actually want to make money and have an audience. Nostr doesn't provide that yet, and one person making the switch isn't going to fix it. It seems silly to put that weight on his shoulders.
