CIA & FBI can neither confirm nor deny they know about these Operating Systems
Gentoo Linux, OpenBSD, and even Windows Vista are hush-hush.

After I published “The CIA invests in these Tech companies”, it was pointed out to me — by one of The Lunduke Journal Community members — that the CIA had rejected a Freedom of Information Act Request for documentation about the Plan 9 operating system.

Not joking. Here’s the rejection letter from the CIA:

The FOIA rejection letter from the CIA.

That’s right. When it comes to Plan 9 (an open source research OS originating at Bell Labs in the early 1990s), “the CIA can neither confirm nor deny the existence or nonexistence of records” about it.

The Lunduke Journal can neither confirm nor deny that this is a screenshot of Plan 9.

Which is pretty doggone funny. I’d like to imagine that Plan 9 is part of some complex spy program. Possibly involving Nazi’s. And space lasers.

But this got me thinking… What other Operating Systems can the CIA “neither confirm nor deny” knowing about?

Let’s find out!

Linux and the CIA / FBI

Well, according to the CIA, they know nothing at all about Gentoo Linux.

This isn’t even a “can not confirm nor deny” scenario… The CIA straight up says, without ambiguity, they’ve never even heard of Gentoo Linux. No memos, emails, letters or reports that even casually mention the existence of Gentoo Linux.

Harsh!

Same goes for Yggdrasil, one of the earliest Linux distributions (from back in 1992).  The government has never heard of Yggdrasil!

How about for Qubes OS (a security focused Linux distribution)? Turns out the FBI “can neither confirm nor deny” that one.

Same with TAILS — a desktop Linux system designed to be used for whistleblowers, journalists, and others who might need extreme privacy. We get a “Neither confirm nor deny” by the CIA.

This time, an appeal was filed… that appeal was… drum-roll please… rejected by the CIA (they’re sticking with the whole “neither confirm nor deny” thing).

But, here’s a crazy bit. The same FOIA request was sent to the FBI regarding TAILS… and the FBI accepted it! Took a little back and forth, but the FBI released at least some documentation showing they know what TAILS is.

As far as I am aware, this is the only Freedom of Information Act Request where a government agency has actually acknowledged the existence of Linux at all. Which is a little amusing.

Also interesting… While the FBI admits to knowledge of TAILS… they “refuse to confirm or deny the existence of” records that shows the FBI actually uses TAILS.

From the FBI’s response to the TAILS FOIA.

OK, FBI. Got it. You can neither confirm nor deny that you use TAILS. Wink, wink. Nudge, nudge. Say know more. Know what I mean, know what I mean.

BSD and the CIA / FBI

What about BSD? Well. It turns out that the FBI is willing to admit a little knowledge of OpenBSD. How much knowledge? One document.

A single, highly redacted, document detailing a time (in 2002) when the openbsd.org servers were hacked. In Canada.

That’s it, and that’s all. Otherwise the FBI claims to have no knowledge of this “OpenBSD” thingamajig.

The CIA, on the other hand, can — say it with me now! — “neither confirm nor deny” that they’ve ever heard of OpenBSD.

Riiiiiight.

Microsoft Windows and the NSA

What about Windows? Surely there’s some interesting stuff the CIA, FBI or other agencies know about Windows!

Well, as it turns out, there is only one publicly published FOIA request — that we know of at the moment — that asks about Windows. Specifically, it requests documents relating to the NSA’s evaluation of Windows Vista.

Seriously.

And, while the NSA admits they have documents about Windows Vista… they can’t let the public know what’s in those documents.

Because… obviously… Windows Vista is a national security issue. Or something.

On the hunt for more

I have yet to be able to find FOIA requests for MS-DOS, AmigaOS, NetBSD, BeOS, PalmOS, Ubuntu, or many others. But I shall not give up the quest!

Because this is just too much fun.

The futility of Ad-Blockers

Ads are filling the entirety of the Web -- websites, podcasts, YouTube videos, etc. -- at an increasing rate. Prices for those ad placements are plummeting. Consumers are desperate to use ad-blockers to make the web palatable. Google (and others) are desperate to break and block ad-blockers. All of which results in... more ads and lower pay for creators.

It's a fascinatingly annoying cycle. And there's only one viable way out of it.

openSUSE says "No Lunduke allowed!"

Those in power with openSUSE make it clear they will not allow me anywhere near anything related to the openSUSE project. Ever. For any reason.

Well, that settles that, then! Guess I won't be contributing to openSUSE! 🤣

The End of the $89 Lifetime Sub is Nigh!

Quick reminder: The massive deal The Lunduke Journal has been running — 70%+ off Lifetime Subscriptions, 50% off all other subscriptions — ends after tomorrow (Saturday, January 31st).

Considering that, here are the steps I recommend:

  1. Grab the $89 Lifetime Subscription before it ends tomorrow night.

  2. High five yourself for saving money and supporting Indie Tech Journalism.

  3. Maybe… grab a donut?

That is all.

$89 Lifetime Lunduke Subs ends this week!

Quick heads up, that the $89 Lifetime Subscription to The Lunduke Journal discount ends… at the end of this week!

Discounting Lifetime Subscriptions by over 70% was an absolute blast. So many of you took advantage of the offer that we’re now up to four Lifetime Subscriber walls at the end of every video. Crazy!

But something that awesome can’t last forever. Which means that, in just a few days, Lifetime Subscriptions will return to their regular price of $300.

With no plans to do another wild discount like that any time soon.

So.

  1. If you haven’t already, snag an $89 (via Bitcoin) or $99 (via Substack or Locals) Lifetime Subscription.

  2. Then let me know if you’d like to be added to the Lifetime Wall of Shame Awesomeness.

My guess is, a the current rate, that 4th Lifetime Wall will be full by Friday.

Bonkers.

And, once again, thank you to each and every subscriber. The Lunduke Journal would not be possible without you.

Lunduke Journal Week In Review - Jan 16th, 2025

Whew! It’s been another wild week for Tech News!

Here’s a crazy stat for ya:

We are currently 16 days into 2026, and The Lunduke Journal has already recorded 19 shows (17 of which have been published on every platform, and 2 others to be published this weekend everywhere… but are already available via the MP4 download page). And that’s with taking New Year’s Day off (and getting the flu this week).

It’s a heck of a lot of Tech News, to be sure.

Lunduke’s Top Stories for the Week

If you only have time to watch a few of shows, I recommend these 3 as being the most interesting (or important… or just… strange) from the last week:

In other words: A pretty gosh-darned crazy week for Linux.

(Those links are to Lunduke.Substack.com, but you can watch all of those shows on any other platform. As always.)

Other Tidbits of Awesomeness

A few other notes on this, most excellent, Friday!

And, with that, I leave you with a screenshot of the MP4 listing of the shows so far in 2026. Bonkers.
