It does not bother me that Jehovah is not the correct way to say God's name in Hebrew.
Nobody complains about using the names Jesus, Moses, David or Abraham, for instance.
We know the Hebrew pronunciations of these: Yehoshua (Joshua), Moshe, Daveed, Ahvrahm. But we all use the English pronounciation.
At some point in time the Jews felt it best not to write out God's name so it would not be marred, desecrated, thrown out or erased. So it began to be written with the vowels of elohim & Adonay.
In time the original pronounciation went into misuse, and thus was lost.
