Putting the governing body front and center has the potential to blow up spectacularly in their faces. Some of those guys are downright creepy. It lifts the curtain and lets people see the wizard behind it.
About a decade ago I went to an international assembly held in Spanish. A few governing body members were there and gave talks in English, which were then translated in real time. I remember a bilingual JW confiding in me that he thought the governing body members sounded very silly. It wasn't what he was expecting. I believe his exact words were that it sounded like they "were reading fairy tales from children's books."
Lots of JWs imagine these men to be wise beyond comprehension and when they see geriatric buffoons instead, you have to wonder whether that will wake a few people up.
