Imagine this scenario:
Step 1) The Governing Body produces a brochure entitled: "Addressing Misconceptions about Jehovah's Witnesses". It brings all the apostate arguments out of the woodwork and addresses them (whether or not the answers make sense doesn't really matter). A few leave the truth as they are stumbled over the content. The rest rejoice that the Governing Body has humbly admitted their mistakes, giving further proof that they are the faithful and discreet slave.
Step 2) After completing a study of the brochure at the bookstudy, a new avenue of preaching is announced: Online Preaching. Different circuits are assigned ownership of different websites to clear up misconceptions about JWs and try to prevent weak or new ones from being stumbled by apostates online. Imagine a few thousand JWs assigned to participate in JWN.
What do you think the net effect would be?
