<<JW proclaim that they are the only people God is using.>>
I agree with this statement but God's HS is not limited to JWs and I don't believe they make this claim as his HS works in many ways in fulfilling his will. If his HS does not operate outside of the JWs then he would not be able to see Armageddon come to fruition or even to aid people who are seeking him to find him. You are claiming that Jackson was saying that he meant the HS was only used exclusively within the organization and GJ made no such claim and neither to they claim this generally.
When GJ said that someone can act in harmony with God's spirit in the congregation in giving comfort and help he did not say anything about exclusivity, he was simply limiting his discussion to within the congregation in this discussion.
They have never claimed that God's HS operates both within his earthly organization and outside it. If you were to ask GJ that if someone was to comfort or help another person using the word of God, the bible, I doubt he would deny that God's HS was not in operation because by following the bible his HS is in operation.
Regarding the claim of being God's spokespeople
<<That
was the question GJ was asked, posted in MS blog. GJ did not proclaim
that he was, using that word. Although the lit may not use the exact
word spokepersons, it does use the word "spiritual food." and God's Holy
Spirit.>>
It matters greatly as to what words are being used and GJ does not deny or agree that they are God's spokesperson. Although he uses other words to express an opinion, they do not answer the original question.
Being God's spokesperson is very different to providing spiritual food. One is speaking for God, the other, providing spiritual food, is using the bible which was provided to us through God's HS by inspiring writers, to provide others with direction as to what God has told us. The bible was written by people whom God appointed as his spokespersons whereas providing the spiritual food is using those inspired words to teach us.

<<So, what can we conclude? When Jesus comes to destroy the wicked during
the great tribulation, HE WILL FIND that the faithful slave has been
loyally giving out spiritual food at the right time to the domestics.
Jesus will then be happy to appoint that slave over all his belongings.
Those who make up the faithful slave will get this appointment when they
receive their reward in heaven and become rulers along with Christ. W13 7/15>>
<<The
related Bible verses state that there WILL BE a FDS that Jesus rewards.
Before the reward, the related FDS has the duty of providing spiritual
food. Since God is the source of the spiritual food they give out, FDS
must have proof from God that they are his appointees and not self
anointed. >>
The related Bible verse does not state that Jesus will find that the FDS is doing what they were appointed to do. The verse states IF he finds them being faithful & discreet then he will appoint them over all his belongings. As you mention that is for Jesus to determine on his return and it is not a given therefore the claim by the GB that there will be an FDS that Jesus rewards is pre-emptying Jesus decision.
Matt 24:45-47 Who really is the faithful and discreet* slave whom his master appointed over his domestics, to give them their food at the proper time?+ 46 Happy is that slave if his master on coming finds him doing so!+ 47 Truly I say to you, he will appoint him over all his belongings.
You say I am going off on a tangent and it may appear that way to you but you made claims that you know what Jackson actually meant yet if your basis for making these opinions is not correct then your assumption as to what he was saying cannot be correct either.
