It's hard for me to think that the Watchtower IT department must be fully aware of WT duplicity as in they are experts in using the internet and are fully aware of what the internet is saying about their boss.
Think harder ;-)
Humans are (unknowingly) experts at compartmentalizing.
I'm an IT guy (in a regular company). I am an expert in using the internet. Yet I never knew what the internet was saying about Watchtower.
Why not? Because I didn't look and didn't search. After all, we have all bee inoculated against the temptation of looking at apostate websites. That same fear or hesitation that most felt when they first visited this site keeps most JW - including the internet savvy crowd - away from websites critical of JW.
Compare it this way: there are many prolific book readers, even among JW. They read many, many books. Does that mean they know what people have been writing about Watchtower? No, not until they actually read a book about that specific topic.
Edit to add: I'm not really fond of clickbait title by the way! It contributes to confusion and fake news, and we don't need that!
