What's going on with so many people defending this as if it's actually better for the consumer? It's not, it's enshittification of the car industry, it's wanting to extract more money from you even after you already bought the car. Doesn't matter that other companies do similar, it sucks and it's worse for everyone because you lose control over the damn car. The argument that you'd save money because you'd get a discount by not unlocking the extra power makes no sense, just buy a cheaper less powerful car
The suggestion of your post is that it's a heinous ripoff. I don't like it, and would find it annoying as a car owner, but I don't think it's quite that bad. It does make it, to me, a bad product.
Maybe an analogy is thus: I find often sports kit that is black or otherwise drab coloured is cheaper. I find this annoying, as I like my kit to be colorful - and I feel like I'm being made to pay extra for color pigment, which surely cost at most pennies more per item. On the flip side, if I go for the black item, it's kind of subsidised by the color-buyers (the comparator is one where black and colorful items cost the same average amount).
The fact that the hardware here is identical but software isn't is IMO an implementation detail.
