One of the weird things is the way manufacturers used emissions regulation as an excuse to lock their engines down.
Older engines had no computers. But computer control allows things that are needed to meet emissions like variable valve timing and whatnot. Also, engines are supposed to detect faults in emissions control systems and throw an error code.
So they brought in ECUs, but they DRMed them. Now they said it's so people can't tamper with emissions, but they DRMed everything to the point where now you have to take it to the dealer for servicing.
Do they need DRM to prevent people from tampering with emissions? No, they could have ringfenced it like some devices with radio transmitters do. Does DRM in the ECU prevent people tampering with emissions controls? Also no. There are people doing EGR deletes and whatnot on Tier 4 engines all the time.
But they were able to use emissions as the wedge to do what they really wanted to do: make their equipment not third-party serviceable.
By the way I think this also is a microcosm of the failure of the liberal order. The government should have cracked down hard on manufacturers doing this to begin with. The fact that they allowed manufacturers to turn their customers into serfs "in the name of emissions" obviously just ended up discrediting emissions control.
