Ding - “…The WT had a long period in which they felt it necessary to comment on all sorts of obscure topics…”
I think there were a few reasons for that…
…Fred Franz’ position as WT Oracle was one… he was a Genesis literalist, and I think he got into that habit as a way of explaining away Biblical things that academic inquiry called into question, whilst still appearing intellectual and scholarly.
…additionally, some followers have always been afraid to think for themselves, and would prefer having an authority figure explain everything to them, and the WT leadership fell into the habit because it was easy and gave the appearance of legitimacy…
…and most importantly, there’s the old authoritarian idea that deep down, people are inherently shitty and stupid, and can’t be trusted to come to the right conclusion on anything without being kept on a short leash and spoon-fed their beliefs.
