Part of freeing myself from the Watchtower cult was to stop using their loaded language. Terms like "Friends/Brothers/Sisters" when referring to members of the organization, or calling the teaching, practices and beliefs of Jehovah's Witnesses according to the Watchtower Society's interpretations as "The Truth".
I found it even easier to stop referring to what others may refer to as God (The Father), or whatever your belief/terms may be, as "Jehovah" was knowing and realizing the organization's printed information on the matter:
According to Insight on the Scriptures Volume 2, page 5 under the heading, 'Jehovah' the following is stated:
"Correct Pronunciation of the Divine Name. “Jehovah” is the best known English pronunciation of the divine name, although “Yahweh” is favored by most Hebrew scholars. The oldest Hebrew manuscripts present the name in the form of four consonants, commonly called the Tetragrammaton (from Greek te•tra-, meaning “four,” and gram'ma, “letter”). These four letters (written from right to left) are ???? and may be transliterated into English as YHWH (or, JHVH)."
The Watchtower Society adds "(or, JHVH)" in their publication, but that letter usage was to make allowance and flexibility centuries later. It does not attribute towards accuracy. The confusion stems from Latin sources, in which the same letter represents both J and Y, and another single letter represents both V and W. Nonetheless, the original Hebrew translates to YHWH.
On page 7, the same publication continues:
"Since certainty of pronunciation is not now attainable, there seems to be no reason for abandoning in English the well-known form “Jehovah” in favor of some other suggested pronunciation. "
So the Watchtower Society is stating that there is no way to attain the correct pronunciation of God’s name, but since ‘Jehovah’ is supposedly so well-known, let’s stick with it. Regardless of the facts that Hebrew scholars use YaHWeH, and earliest documented evidence shows YHWH – Not JHVH [JeHoVaH] as valid consonants in the name.
The Divine Name brochure on page 7 under ‘God’s Name – It’s Meaning and Pronunciation’ makes the following statements:
“How Is God’s Name Pronounced? The truth is, nobody knows for sure how the name of God was originally pronounced."
There is more information, but the above alone was plenty enough for me to easily stop using "Jehovah" as the name of "God".
