Jehovah`s Witnesses stated in their publications notably the book "Aid To Bible Understanding " that they settled on the name "Jehovah" because it was the name most commonly used in the world for God ?
And who would be the ones in the world that would be the most likely to use Gods name ?
No prizes for guessing it would Christendom and all its Scholars /clergy and bible translators ,authors etc,etc.
I attended a funeral not so long ago for a friend and one of the songs in the service had the name Jehovah a number of times in it and that was an Anglican service.
Also many years ago the WTB&TS put out a booklet about Conventions that was happening all around the world containing photo`s about the worlds religions and it was shown that many churches around the world in Christendom had the name Jehovah inscribed in stone on the buildings .
This was about the 1970`s-1980`s ? and it may have had to do with "Babylon The Great Has Fallen " theme ?
As well their are many translations of the Bible in Christendom that contain the name as either Jehovah / Yahweh or some other equivalent.representing the four Hebrew letters of the Tetragrammaton commonly translated as JHVH or more accurately as YHWH .
So they are blatantly dishonest in saying Christendom has hidden the name of God from their members .
