My contention is that the definition of said product and its inherent capabilities is being gatekept by a corporation that would love you to buy both an iPhone and Mac, and treat them as separate. In fact, I do have both already! But I still want rights to modify my iPhone as the computer it is. The MacBook Neo is a great example of just how fungible these categories are, at least as far as the SoC that runs them is concerned. I paid for my iPhone in full, there is no reasonable justification for why I can’t repurpose it / modify it as I see fit.
