> Obviously I still own the car. Do you still own the car if it'll just turn off the engines when attempt to drive into a sketchy neighbourhood? Let's assume the car manufacturer knows the city/town's crime rates well and they have your best intentions in mind. They want you to be safe. Do you still own the car?
If I bought a car knowing that is how it worked, then of course I do. Note: I agree that scenario isn’t desirable. However there is no slippery slope.
The problem is that they (have the ability to) continue to make those decisions afterwards. You could have "known" an iPhone could run Fortnite at the moment you bought it and then after you received it in the mail discovered that they had decided you were no longer allowed to do that.
You could then say "well I bought it knowing they had the ability to change anything at any time" but I'm not sure I agree that you can give informed consent to a blank check.
