IMHO mainly that and clearly those trains are required to be designed in such a way that they could be repaired by a third party (either by law or by contract based on how the situation is described).

Apple provides (nor is required) no such guarantees. Also it has more or less legitimate reasons for its design decision (making it harder to reuse stolen parts).

I certainly disagree almost completely. With Ape you know what you’re getting and can make an inform choice. Also it’s a completely different type of product. Trains have various regulatory, safety and maintenance requirements which are irrelevant for consumers devices. Screwing with the software controlling trains can literally kill people..
