Let me clear up some wrong information here, as there is Jalopnik levels of it.
1. Car manufacturers currently do not add more things than the ones ordered, each wiring harness is tailor made for the specific car and only has the connectors for the ordered spec. This has to do with cost and weight saving, but does create a higher complexity & part numbers in plant.
2. If you flash your ECU, manufacturers can, and will, detect it. If you return a lease car, it will show if the ECU has been modified. Just because it doesn't notify you it doesn't mean the car and company don't know.
3. Tesla went a lazy way of locking their addons, I know of one German manufacturer that actually used the Tesla case to get more funding for a proper way. There won't be any black boxes or hacking with this.
4. The B48 4-cyl Petrol engines are available as 192, 224, 231, 252, 258 and 306hp variants. It's a combination of tune, exhaust, cooling pack and internals. Good luck running the same boost of the 306hp variant on the 192hp engine.
5. You can still spec your car with whatever you want & can afford and it will stay with the car, the subscription service is for you to test options or upgrade your car later once you decide you want something / can afford it
6. Most of the subscription stuff uses things already installed in the car. Adaptive cruise? Uses radar sensor and cameras required by EU law for city emergency braking. Adaptive LED light? Cars come with LED headlights as standard, you reduce variants in plants if you only install one headlight on each car, and the matrix function gets enabled later via software. Drive recorder? That's the EU city cameras again. Lane assist? Cameras again. Exhaust sound design? Uses speakers. I could go on, but in the end, it's a combination of using stuff that's already there and reducing variants in plant, therefore cost saving. It allows people to upgrade a car they bought, and also makes used cars more interesting because you could theoretically spec it like you want after buying it. Fact is, people these days mainly do want the flexibility to have everything as a service, see Uber, Netflix, Car & Bikesharing, Spotify, even leasing cars.
Here, have a nice article from Siemens:

And let's be brutally honest. The people in this forum (myself included) mostly own rather older speciality cars, we are not the people who exchange their leasing car every three years. Therefore this forum is an echo chamber of "THE GOOD OLD DAYS" "THE CAR INDUSTRY LOST THEIR WAY" "I WILL NEVER BUY A NEW CAR AGAIN (which you never have before anyways)".
So yeah, if the automotive industry wants to survive and compete with people like Tesla, who fully understand that OTA upgrades, payable services etc. are the way to go, they need to adapt and compete. If they don't, they will die.
Right now, we are here:
And now, observe the news who is currently on the way out.
My prediction is that this list will shrink to max. 10 in the next 10 years.
First casualties I predict will be Geely, Mclaren, Subaru, Tata, FCA or Suzuki.
