Hey, I do high-assurance systems too. High-assurance security where input or environment might be malicious. Even in my constraints, the systems are designed so the parts can be replaced without magic software. The big complaint about JD seems to be them using software constructs to prevent fixing tractors or common extensions. The former should not be hard as JD just has to allow products with certain specs for what will work. The second might require a combination of that with a more manual, operating mode with some automation disabled. Less complexity than what JD is putting in there. So, Im not buying it even if you worked on the team. They could design it for cheap fixes for parts easily. They could allow more extensions than they let on by turning off some automation. They are instead applying the well-tested concept of lockin both with software and their request to copyright office to make mods illegal. This is to increase profit of their near monopolistic dominance of a lot of the market (esp rural areas).
