On the flip side, it can often be the only option for businesses that need equipment. The US has a longstanding trend of hacking John Deere tractors to accept third-party servicing since John Deere's first-party offerings are both expensive and often unavailable.
And getting sued by a train manifacturer is typically a asymmetrical battle for a private person. Consider watching the original talk (very entertaining and insightful, probably one of the best hacking related videos I watched in 2024), and if you like them toss them a tenner or so.
When you intentionally design systems with purpose to delay, but overall sabotage, you show malice and you defraud the purchaser (after-the-fact), you also interfere with their business with third-parties, and impose coercive costs that have never been acceptable.
Coercion is generally not accepted by any civilized society that still follow its original founding principles, and coercion and corruption tend to go hand-in-hand.
Apparently its a critical component.
If companies that did this got jailbroken and blacklisted by the government, pretty much nobody would try this bullshit.
