They overinflate themselves, but the reality if that they are quite mediocre in everything they do.
Yet, WT has been so successful containing the paedophile files that various courts continue to demand access to. If WT's data security is so inept or at least mediocre, it's surprising someone hasn't successfully accessed and circulated even a portion of that database.
I believe "leaking" supposed inside information, is often employed by corporations of all types, as a means to build anticipation, excitement. or create buzz for the company or its products.
Consider that although Apple does not outwardly release specifications, designs or technology advancement plans for its next iPhone prior to an official release announcement, whenever there is an advance 'leak' regarding that info, the tech news world goes nuts wanting to be first to report leaked info, whether factual or not.
I think 'leaks' serve Apple well as someone considering a new phone prior to Apple's release announcement, may decide to delay the purchase of another brand, to at least confirm if the leaked iPhone info is actually true and further consider if the new iPhone might be worthwhile.
The WT 'leaks' we see on this forum, whether regarding WT finances or other matters, typically result in numerous long threads and plenty of speculation presented as fact. While info that is leaked may not be totally false, it may not be necessarily complete or may be worded in a way so a reader might be lead to conclude things that are not totally factual.
If I was WT and I have 'enemies' (Ex-JWs) that are like pit bulls, constantly examining everything I do and attempting to bite me in the butt, I might be inclined to throw them a meaty bone every so often so as to distract them and get them off my back.
