As Jehovah said to the Israelites "you are my witnesses" and was happy to let them get on with things without major interference by him, he must have broadly approved of what the nation was doing, until Jesus came and changed things.
For hundreds of years before Jesus the JW's (Israelites) had decided that the Name of God was too Holy to pronounce. Had He been upset by this He would have sent a Prophet to sort this out, but no, it continued as practice,for 200 years at least,and remained uncondemned by Jesus.
If Jehovah had really wanted His people to use His name, would not a prophet, at least would not His son, have said so ?
