In 2000, I wrote a Linux device driver that “decrypted” the output of a certain device, and my company, which hosted open-source projects, agreed to host it.

The “encryption” was only a XOR, but that was enough for the maker of said device to sue my company under 17 U.S.C. § 1201 for hundreds of millions in damages.

The story got a lot of press back then because it highlighted how stupid the then-new DMCA was, and also because there was a David open-source enthusiasts vs. Goliath heartless corporation flavor to it.

Our lawyer decided to pick up the fight to generate free publicity for our fledgling company. For discovery, the maker of the device requested “a copy of any and all potentially infringing source code”. They weren’t specific and they didn’t specify the medium.

So we printed the entire Linux kernel source code including my driver in 5-pt font and sent them the boxes of printouts. Legally they had been served, so there was nothing they could do about it.

        The year is 2025. A massive geomagnetic storm has fried all forms of technology, wiping out hard drives and solid-state drives alike, and scrambled all backup tapes. Coincidentally, a new plastic-eating bacterium has munched on all the compact discs without anyone noticing.

        Humanity will rebuild…

        The computer chip manufacturing pipeline has been restored, but there is no software to run them. In a dusty office previously owned by a lawyer from a long-defunct dotcom, a treasure trove is discovered. Five metal cabinets filled with paper: the printed Linux kernel source code, in 5-pt comic sans font. One brave soul will enter to transcribe. Mistakes are not an option. We all thank you for your sacrifice.

    I stare at Linux source code very often looking for vulnerabilities.

    I unironically have printed pages out to sit down with.

    The idea of having the whole kernel printed… is… fun. Lol. How would your organize it for reading? Different chapters that are the directories of the kernel code ?

      I’d love to hear more about this - do you do it professionally (for preventative reasons), as a side hobby, or as an attacker for malicious/selfish reasons? No judgement, genuinely curious as it takes a certain personality type to do this kind of work and I find it really interesting.

          Neat. Why is Linux kernel relevant for many mobile users? Is iPhone built off of it the same way Mac OS is?

            MacOS and iOS have Darwin as their base, which is really a mutt. Apple started with the NeXTSTEP kernel, which was a mix of 4.3BSD and Mach, then folded in some FreeBSD, other open source components, and some in-house code.

            It’s Android that uses the Linux kernel as its base, and the millions of phones makes it a juicy target.

              Not too surprising that iOS has linux in its DNA, but never realized Android does too. Always assumed it was more windows-based. Good to know.

                iOS doesn’t have any Linux.

                FreeBSD is not Linux. Linux is a kernel and Apple uses Mach, a different kernel. They do both share that they’re POSIX, but OS X is actual, factual, UNIX, and Linux has never paid the money to qualify.

                  How different is the FreeBSD kernel from the Linux kernel?

                  Like in terms of interfaces, if I were to port a device driver, am I just changing some header files and some constants/enums/ifdefs?

                  Or there’s like entirely different function signatures / APIs?

                  My bad I’m conflating bash and Unix. From my end both apple and Linux use bash so they have the same underlying base…but I realize that’s not accurate, and even unix and bash are not synonomous.

    Legally they had been served, so there was nothing they could do about it.

    Somehow I doubt this.

    Maybe it’s true but legally I know in California you are required to do your briefs in 12 point font. While that’s briefs, I would imagine evidence would be under the same banner. It definitely WOULD be illegal to do it in 1 pt font or intentionally making it unreadable. I would imagine if the other side wanted to make it an issue they could back to the judge and he’s probably have it out with you.

    Maybe the lawyers wisely replaced your malicious compliance with correct sized print with out telling you, maybe the other side didn’t care.

      I don’t think the font size matters too much in this, it’s just the printing the whole source code, including a lot of not directly relevant things, and sending all of that over in a few boxes instead of sharing the project files with them that is very malicious.

        It’s also very common in legal cases to share evidence printed out, instead of in digitally, to make sure it isn’t easy for the other side.

      I don’t know. I didn’t do the printing. The law firm did it. But I remember our lawyer mentioning that they fedexed over 20 cartons of printing paper. Assuming 500 sheets per ream and 5 reams per carton, that would be 50,000 sheets, or 100,000 pages since it was printed on both sides to be even more annoying.

          No idea. That company folded before it could even respond. It was a typical dot-com with a completely ridiculous business model. That’s why our lawyer decided to fight the suit: he figured they’d collapse soon anyway, so we might as well milk the lawsuit for the publicity.

          As somebody who lives in an area with an active logging industry, I can tell you that parts of the world with an economic interest in their forests still have lots of trees whereas areas that do not are very likely to have destroyed most of theirs.

    I was a tech journalist in the early 00’s and I remember writing about that story or one like that.

    A similar thing happened with Microsoft, who either delivered or was served the full documentation of some office format printed out. It’s a pretty popular form of malicious compliance, also paying people in bags of coins.

      Now that’s a name I haven’t heard in a long time.

      The guy who invented it sounds like a certified nutcase.

      In 2016, Pulitzer appeared as a treasure hunter on The Curse of Oak Island on the History Channel. He searched for the Ark of the Covenant and working with amateur historians from the Ancient Artifact Preservation Society he claimed that a sword found in the waters off Oak Island in Nova Scotia had “magical magnetic properties” and was evidence of Roman presence in North America and contact with the Miꞌkmaq, which a historian of that people dismissed. An archaeologist and a science writer criticized Pulitzer’s claim, suggested the sword was a replica said that Pulitzer threatened to sue them.

      Certainly sounds like the same guy.
