How do you know what God wants? “He would want it like this. He wouldn’t want that.” Where does that come from? Maybe he is happy with his name being used in somewhat different forms in hundreds of languages as JWs do. For all we know. Why not? Other than your say so.
Another issue is the meaning of the name. JWs have leaned in pretty heavily on the meaning of the name coming from the root verb “to be”, and that it signifies that Jehovah becomes whatever he needs to become in order accomplish his purpose. That’s a pretty interesting and distinctive theological position, in my view, and presents a more compelling understanding of God’s interaction with humans than an austere Calvinist, predestinarian view.
If JWs are 1) right that God still wants people to use him name 2) they’ve got the meaning of the name right, and 3) the implications it has for his character and interactions with humans in accomplishing his purpose: that’s a pretty interesting and distinctive set of things for a religious group to have correct. On top of that you can’t actually say for sure that Jehovah, or more likely the German Jehova, is not fortuitously close to ancient pronunciation, because even scholars who promote Yahweh will most often admit that it isn’t certain either. As I indicated earlier, the idea of a correct original pronunciation is problematic anyway, because it seems highly likely that it changed over time, and Isaiah, Nehemiah, Jesus and others would all have said it differently from each other anyway.
