Yes? But if you want to solve that issue locking down the tech is not the solution. The solution is to have an inspector show up unannounced and give you a hefty fine if that screw is set incorrect.

So if that is really an issue, apply the correct fix and don't push the blame on environmentalists.

I think I disagree. I think the administrative overhead makes for additional problems and is certainly imperfect at mitigating the risk.

Risk mitigation (where the risk defined here is emissions outside some acceptable threshold) usually follow this hierarchy from most preferrable to least:

- remove the hazard (make it impossible for emissions to exceed the limit, even by altering the operation)

- install an engineering mitigation (filters, def, altered fuel mapping etc.)

- administrative mitigation (training, inspections)

- protective equipment (?? make everyone in society wear a mask?)

In this framework, a technological solution is preferrable to an administrative one.
