Tangential to your main point t_b_k -- but what the situation demonstrates is the nature of the "language of indoctrination". Apostate lies means more than lies told by apostates.
As in your example, clearly it covers the critical assessment of non apostates. It covers the meaning of apostate truths as well but Bethel writers cannot give any ground to the possibility that apostates could actually ever talk truth or report facts.
The phase "apostate lies" coming from HQ is loaded language and it speaks only to JW true believers.
Firstly it suppresses thinking or analysis. It comes with a layered meaning, it demands by flagging up a warning: have nothing to do with this information because the whole of it is contaminated, don't investigate, don't listen, don't believe it. This feeds into the naive division that there are only two possibilities of choice in life namely Satan's world or Jehovah's. (In each case these two camps are part of the loaded language as well).
The JW is groomed to respond unthinkingly to the specific language of HQ and part of the compact he or she makes (unwittingly) with the governing body when joining the sect is to relinquish private thoughts and submissively conform to their instructions.
So very sad for the believer and abusive on the part of the governing body of Jehovah's Witnesses.
