Maybe it’s bad advice that ne’er-do-wells will try to employ, leaving them susceptible to the CIA.
There's just so many spooks and bad actors about. Having some familiarity makes for a more educated populace who are going to be more wary of being manipulated, so there is really no reason to try and reserve this information for an elite. Because the bad actors are very grateful when you do: they will prosper in a field of targets all of whom are super naive.
Wouldn't it be dangerous to publish bogus info that can be picked up by nationals and allies, especially since it is branded?
Say you want your adversaries to use pencils instead of pens to write their secret notes. You publish information on the risks of pens and how they leak information on an obscure corner of the internet and seed it to a small forum or two. That gets picked up by a government worker in Germany and they put it into their recommendations. That document then gets stolen by the Chinese. Both of these get shared with Iran. The materials are then leaked and you have the Snowden's of the world shouting from the rooftops the importance of using pencils.
Then it worked perfectly.
Its probably just to drive interest for recruitment since tensions are escalating geopolitically and they are probably finding their projections show they are understaffed. Skilled labor isn't as easy to come by as corporations make it out to be (with everything being replaceable).
Anything published like this would be considered a poison the well attack by any ne'er do wells.
