It's the year 2022 and we're sideloading tractors.

  Surely John Deere are releasing source code to farmers and giving them the build instructions and install instructions needed to update the code on the tractors? /s If the Software Freedom Conservancy win their lawsuit against Vizio, this means that farmers across America will be able to sue John Deere for GPL compliance. https://sfconservancy.org/copyleft-compliance/vizio.html https://sfconservancy.org/copyleft-compliance/vizio.html

    Assuming John Deere suddenly complies with the GPL, then what? The kernel source code is a tiny fraction of the actual software that makes up the entire product, and as far as I know no where does the GPLv2 require you to provide build instructions, let alone a way to flash new software?

      You're right that most of what makes Deere tractors useful is probably proprietary, but once the base layer is open source, modifiable and reinstallable, then you can start building open source components on top that do everything else. We saw that with routers, the OpenWRT distro started out as a bunch of basic low-level code from a GPL compliance case and now there is a full-featured comprehensive web interface and a full OS for routers that is open source and runs on a variety of hardware. https://sfconservancy.org/copyleft-compliance/firmware-liberation.html https://sfconservancy.org/copyleft-compliance/firmware-liber... It is a common misconception that GPLv2 doesn't have build/install requirements, GPLv2 does actually require users to be able to both rebuild and reinstall the GPLv2 parts. https://sfconservancy.org/blog/2021/mar/25/install-gplv2/ https://sfconservancy.org/blog/2021/mar/25/install-gplv2/ https://sfconservancy.org/blog/2021/jul/23/tivoization-and-the-gpl-right-to-install/ https://sfconservancy.org/blog/2021/jul/23/tivoization-and-t... https://events19.linuxfoundation.org/wp-content/uploads/2017/11/Safely-Copylefted-Cars-Reexamining-GPLv3-Installation-Information-Requirements-ALS-Bradley-Kuhn-Behan-Webster-1.pdf https://events19.linuxfoundation.org/wp-content/uploads/2017...

We've gotten to the point that in the future at the coffee shop you're going to have farmers asking each other, have you jailbroken your new John Deere?

  In this context, I think one can assume some high level of commonality between the implementation of the security of the different John Deere products. So, phrasing it as a group makes some sense.

      Lack of detail doesn't make something wrong. You are the one who is wrong here. Is English perhaps not your first language? I'm having trouble imagining how a native speaker could think referring to a specific tractor as "a John Deere" is somehow incorrect English.

      > Then why is the singular “a” used? Because that's how English works. You can drive a Tesla, own an Andy Warhol, and jailbreak a John Deere.

        Tesla makes one thing: automobiles. Andy Warhol made one thing: paintings. John Deere makes many things: tractors, lawn mowers, displays, harvester combines, excavators, and many more things, including stuff that works in non-john Deere vehicles. "jailbreak a John Deere what"
