Don't you suppose you're being a bit dogmatic about it? Every device has to be as flexible as possible or it's against the law? Genuinely not trying to straw man, but should my oven manufacturer have to account for me wanting to turn it into a space heater if I feel like it?

Companies make and sell products for specific use-cases all the time. Saying the can't sell something unless they also make the product able to break away form that specific use case, regardless of time and cost to the company and consumers for parallel built in systems or whatever the lift may be doesn't sound feasible to me.

I don't know, I'm on your side that I should be able to dismantle my iPhone and use the parts to my hearts content if I want to. But I'm not sure that it's something Apple has to build into the system just in case someone feels like doing it, especially since I could buy any number of other computing devices that might work just as well.
