NotFormer, actually there was a WT article in 1970 with a title with the phrase "Men of Goodwill"
It has many uses: for non-anointed jws that were "associates" of the anointed jws
And, finally people outside the WTS, who were somewhat "favorable" to the WTS message. The WTS also confusingly sometimes made the great crowd/other sheep not being included with "jehovah's witnesses" as if only the anointed were jws. As late as 2002:
The modern history of Jehovah’s Witnesses attests that they have been succored by their loyal companions, the other sheep, as these were moved by the spirit.
1950:
How do Jehovah’s witnesses and their companions praise God?
1951:
voluntarily from Jehovah’s witnesses themselves, from their associates, companions, persons of good will,
1965: Jehovah’s witnesses and their companions, are the only ones in the earth who are praising and blessing the most important, the most wonderful and the most holy name in all the universe, the name of Jehovah!
