Yeah, that’s a good way to summarize what people are mad about; they basically moved all of the calibration from onboard to offboard diagnostics, and then thwarted most efforts to access the offboard diagnostics.

Automotive is similar and I’m a bit worried for EVs; for ICE autos there’s enough emissions related regulation that some diagnostics and manuals are accessible, but for EVs there’s nothing much stopping a Deere style complete lockdown.
