Do you feel that console makers shouldn’t be allowed to dictate what runs on their devices? Yes physical discs still have to be approved by the console maker. It’s been that way for 30 years.
Yes of course. Either allow the user full control of the hardware they apparently own, or call it what it really is, renting.
You could have an argument in the case of a car, for safety. Cable box perhaps, but I'd say that should probably be considered a case of renting hardware for it to really make sense.
Car radio or printer, etc? Nothing comes to mind.
*EDIT: i’m not saying “place and purpose” is a reason why macos and ios have different security models, but just pointing out that “why is a laptop different to a phone” is not reeeeeeally a particularly valid place to start
Um really those are artificial, not natural. The nature of the devices is that they're still general purpose computers, the artificial restrictions on them give them an artificial place and purpose. It's still a thing, but Apple isn't magically altering reality.
If not, how is it any different from the phone?
