I think it is worth seeing the quote in more context. Of course it does not mention AM3, but says this.
“12 Psalm 15:3 also reminds us that Jehovah’s guests do nothing bad to their neighbors and do not defame their friends. What might that involve?
13 We could unintentionally defame someone by spreading negative information. For example: (1) a sister discontinues her full-time service, (2) a married couple no longer serve at Bethel, or (3) a brother is no longer serving as an elder or a ministerial servant. Would it be proper to speculate on the reasons why these adjustments were made and to share that opinion with others? There may well be reasons for the change that we are unaware of. Furthermore, a guest in Jehovah’s tent “does nothing bad to his neighbor, and he does not defame his friends”
