Of course, the logical corollary to all your observations is that the Witnesses are complete failures. JW's believe that it has been their job to inform people about the 'Cosmic courtroom' for many decades now. That commission is one of their proudest boasts.
But you can ask one hundred people on the street, "What is the universal issue facing mankind?" or "How will the challenge to Jehovah's sovereignty be settled?" or "When will God's name be vindicated?"
Nobody would know. Those questions are so alien and outlandish to the average person that if you actually tried this in a small town, there's a good chance you'd be locked up.
You could try more generic questions like, "What is God's kingdom?" or "What is God's name?"
You still wouldn't get the correct JW answers. Any way you look at it, the JW's simply have not done what they've proclaimed their job to be.
Remember being at someone's door in field service, and them finally saying "oh, so you guys are Christians; cool!" and you'd feel good that at least they'd gotten that out of your conversation, even as you felt bad that many worldly people didn't already think of JW's as "Christian"?
One of my first thoughts upon leaving the org was "geez, 130 years of tireless preaching, and we haven't even managed to communicate to the world that we're Christians?".
