The example is of course egregious ($600 for a software update for a wire that got wet, basically). I fully support being able to repair your own stuff but I have no idea how you regulate this so companies don't gouge "owners" for aftermarket services. Earlier today there was a thread about e-bike battery prices (tl'dr they're ridiculous expensive). I really wish rechargeable batteries had interchangeable form factor…
For starters, it's not aftermarket! since the tractor belongs to JD, and it is licensed to the customer, and it failed to work because a wire got wet (shitty design), and only JD can determine and repair it ... that should be JD's cost, not the owner's.

A harsher one: JD has a monopoly and is using it to strangle its own small business customers. Feels good to see it get run past Sherman - better to see it get run over.
