The really offensive part of this kind of thing is that you already paid for it. Like if you wanted to buy a regular car and you could get the engine with turbo then those are two different cars. The latter costing more because it has more/better stuff in it. This is all fine and good. In this case, all the cars have turbo and you pay to have it turned on or not. The cost of the turbo is in the cost of the normal car…
As I said in other comments, this is already happening since years (and I mentioned Ford, but literally everyone else does it). Car manufacturers already give you the same powerful engine that you can't afford/don't want to buy and "shrink" it with SW. If you jailbreak it, you lose the warranty and bye bye insurance. You should not think that you're paying more for getting less. You should think that finally you can…
TFA already says the car is registered at the maximum power level regardless of the actual software cap. So you are _quite literally_ paying for it, at least in terms of increased insurance and taxes.
