It's the November 2016 Watchtower. They make this claim on page 9 para 6
Living without the help of God’s organization and his standards would result in unhappiness and misery.
Another very bold claim, stating that in order not to have unhappiness and misery we need the help of JW dot org.
Then there is this statement para 9 page 16
Some may feel that they can interpret the Bible on their own. However, Jesus has appointed the ‘faithful slave’ to be the only channel for dispensing spiritual food
The question for that para is "9. What is the only channel that is being used to help us understand God’s Word? "
YouTuber Michael Felker asks whether it's really true that someone cannot interpret the Bible on their own and which parts can he interpret on his own and which parts can't he because it can't be denied that there are parts of the Bible that can be read and understood by the individual.
Regarding para 10 and the mention of Jehovah's chariot Youtuber Michael then asks how do we know when the org. makes changes that they are moving closer to the truth or further away? The measuring stick is always what is put in place by the GB. So if the org. goes up or down so does the JW and the individual therefore has no way to go except up or down along with the GB. Which means going closer to the truth or away from the truth. How can they say that Jehovah is behind that development? The problem is that they are blaming Jehovah for the decisions of the leaders.
