I already explained why it's not a good example in my previous reply: because with the detuning example (and I'm not endorsing the business practice of engine detuning either), the buyer pays once and then the car (and the engine) is theirs, forever. There is no monthly fee. The transaction is done.
Also, regarding your assumptions about me, I'm actually a millennial, and probably more open-minded than most. But if me wanting to actually own the physical objects that I purchase and not have some company add on a completely unnecessary, internet-connected padlock around them to prevent me from using them unless I pay them a monthly "unlocking" fee makes me an "old dog", well... then get off my lawn!
