Ownership gets weird when software can say no

If you buy a $300k tractor, what should you legally be allowed to do to it? The part that bugs me is how often “repair” turns into “wait for the manufacturer to unlock the thing you already paid for.”

I get the safety argument in a few cases, but a lot of this feels like rent-seeking with a nicer label. Curious where people draw the line between legit safety controls and software DRM dressed up as maintenance.
