All of the posts I see nearly universally mourn its loss, most of them condemn the decision, and most of those assign it nefarious motivation. While any of it might be true, and the lack of comment by the agency begs for theories to be invented, I'm surprised that I've seen nobody raise the obvious motivation. I don't see it as much different than the old Encyclopedia Britannica set that I used to go to when I needed information: It's expensive to maintain and few people use it these days.
During the Factbook's heyday, there was no / little WWW, and it was difficult to get current, relevant information on the outside world; much of what you could learn was from, hmmm, an outdated encyclopedia. Nowadays, aside from Wikipedia you have numerous primary & secondary (and lower, sometimes pretending to be P/S...) sources of info on the web, and while it's not always put together in such a nice compact useful format, nor do you know who all of it comes from, the sheer volume of info at our fingertips and its ease of access surely means that fewer and fewer people rely -- or need to rely -- on the CWFB.
Meanwhile, the cost of maintaining that publication has not dropped the same way. Can you put yourself in the position of managing the agency's budget, wanting to spend money on your actual mission, and continuously looking at this ancillary project that consumes a huge chunk of change and provides you little benefit -- that few people even know is there, anymore? The CIA's job isn't to provide the world's citizen's a free collection of info about everyone from its point of view, no more than it's the Census Bureau's job to give every company's marketing dept. detailed demographic info on everybody; those things are just nice side benefits.
Now maybe the CIA can use the money to improve its own internal references, with what *it* cares about, without worrying about what's going to make everyone else happy.
I do realize that there are good reasons to encourage them to keep it alive and healthy, but I also think that there is valid motivation for the CIA to stop paying for it. If any of you want to step up and take the info to start a new World Factbook, I invite you to, and hope you get support from others who see its value. Maybe you'll even get the CIA to contribute an employee or two to influence it.
