@JohnJBurnsIII @q3k it reads to me as "DRM to ensure that orgs who bought the trains were only using maintenance contractors authorised by the manufacturer" and I'm pretty sure that there's regulation against that kind of thing in other vehicles (cars, say)
@outie @JohnJBurnsIII @q3k yeah, I think you're missing the story here, John. It's the train manufacturer doing very sketchy stuff to try and prevent operators from having them maintained anywhere but their shops. Like if your car maker slipped some bogus code in that made your car refuse to start if you had it serviced at the local garage. Or your phone manufacturer doing the same, ahem, Apple.
